Brookhaven Scientists Create a New Nanostructure

 

Scientists from the U.S. Department of Energy's Brookhaven National Laboratory have devised a method to create a new, intriguing nanostructure: ultra-thin, ribbon-like "nanobelts" bound to nanotubes. Their research achieves several "firsts" in the field of nanoscience, the study of materials on the scale of a billionth of a meter. Additionally, the new structure, described in the June 4, 2005, online version of Nano Letters, is likely to have unique electrical and mechanical properties, and may be useful in many developing nanotechnologies.

"We have produced nanobelts that have controllable thicknesses of about two to five nanometers. It is significant work, since the controllability, the thinness, and the methods we used are all new achievements," said Brookhaven materials scientist Wei-Qiang Han, the study's lead researcher. "But, we are most excited about creating a brand-new type of nanostructure." ...read the wave

UC Berkeley, LBNL researchers shuttle ions through nanochannels to produce first nanofluidic transistor

 

Berkeley -- University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first "nanofluidic" transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels.

The researchers - a chemist and a mechanical engineer - predict that, just as the electronic transistor became the main component of microprocessors and integrated circuits, so will nanofluidic transistors anchor molecular processors, allowing microscopic chemical plants on a chip that operate without moving parts. No valves to get stuck, no pumps to blow, no mixers to get clogged.

"A transistor is like a valve, but you use electricity to open or close it," explained Arun Majumdar, professor of mechanical engineering at UC Berkeley. "Here, we use a voltage to open or close an ion channel. Now that we've shown you can make this building block, we can hook it up to an electronic chip to control the fluidics....read the wave

Researchers at Rensselaer Create Multifunctional Brushes From Carbon Nanotubes

The nanobrushes could benefit the electronic, biomedical, and other industries

 

Berkeley -- University of California, Berkeley, researchers have invented a variation on Troy, N.Y. — Researchers at Rensselaer Polytechnic Institute have created a line of brushes whose bristles, made from carbon nanotubes, are so small that a thousand of them could fit inside a strand of hair.

The carbon nanotube brushes already have been tested in a variety of tasks that range from cleaning microscopic surfaces to serving as electrical contacts. The brushes eventually could be used in a whole host of electronic, biomedical, and environmental applications, says Pulickel Ajayan, the Henry Burlage Professor of Materials Science and Engineering at Rensselaer, who is heading the research.

The research, in collaboration with the University of Hawaii at Manoa, will be published in the July issue of the journal Nature Materials. Rensselaer postdoctoral associate Anyuan Cao, working with Ajayan, is the lead author of the paper.

The brushes look like microscopic toothbrushes, brooms, and paintbrushes, with handles the diameter of a human hair. Each brush is composed of millions of carbon nanotubes, each about 30 nanometers in diameter. The brushes have been tested manually and with rotating electric motors...read the wave

Fujitsu Group and Kanagawa Academy of Science and Technology Successfully Fill Anodic Alumina Nano-holes with Cobalt

 

Tokyo (JCNN) - Yamagata Fujitsu, Fujitsu Laboratories, and the Kanagawa Academy of Science and Technology have jointly succeeded in filling up anodic alumina nano-holes with cobalt, a magnetic metal.

The partners have developed a technology to linearly align alumina nano-holes by creating irregularities at intervals of 45nm on the aluminum surface in a linear fashion.

They have discovered that nano-holes are created in concaves and they are not created in convexities.

The joint research group has applied electroplating to fill the nano-holes with cobalt.

The technology will pave the way for developing an ultra-high-density recording medium capable of recording 1-bit of data in a magnetic nano-hole.

The partners are aiming to achieve a recording density of 1 Tbit per sq. inch. SOURCE: JCN Network

SIZE MATTERS: FRICTION, ADHESION CHANGE ON ATOMIC LEVEL

 

Physicists have a pretty good idea of what to expect when friction and adhesion occur in the visible world. You jam on the brakes, for instance, and your tires and the highway interact to stop your car. You glue two pieces of wood together, and they stick.

But how slippery or sticky are things that are too small to see? When solid surfaces no more than a thousand atoms across brush past each other, will they respond like the rubber and the road? Will they adhere like the wood and the glue?

The answer turns out to be "It depends," according to Johns Hopkins physicists who used computer modeling to examine how friction and adhesion operate on the atomic level.

"Any surface made of individual atoms has 'bumps' of atomic dimension, and being able to vary the placement of atoms [in the computer models] allowed us to quantify the influence of atomic structure," said Mark O. Robbins, a professor in the Henry A. Rowland Department of Physics and Astronomy in the university's Krieger School of Arts and Sciences...read the wave

Bubbly Channels

 

Luminescent quantum dots of semiconducting materials could eventually help to identify tumors, illuminate large flat-panel monitors, or make optical data processing a reality. Quantum dots are nanoscopic crystals so small that their chemical properties are similar to those of individual molecules. Researchers at MIT have now developed a microfluidic technique that delivers tiny crystals of particularly uniform size - and thus excellent optical quality.

Cadmium selenide quantum dots are usually obtained by injection of precursor compounds into a hot solvent. Many factors, including local temperatures in the reaction vessel, concentration gradients, as well as the rates of mixing and the final cooling process, substantially influence the results, but are difficult to control.

TINY BUNDLES SEEK AND DESTROY BREAST CANCER CELLS

 

A Penn State College of Medicine study shows for the first time in an animal model that ceramide, a naturally occurring substance that prevents the growth of cells, can be administered through the blood stream to target and kill cancer cells.

"Ceramide is the substance that accumulates in cancer tissues and helps to kill cancer cells when patients undergo chemotherapy and radiation," said Mark Kester, professor of pharmacology, Penn State College of Medicine, Penn State Milton S. Hershey Medical Center. "By boosting the amount of ceramide through an injection in the bloodstream, our study in mice suggests that we can provide a stronger cancer-killing therapy without additional side effects."

This study, titled "Systemic Delivery of Liposomal Short-Chain Ceramide Limits Solid Tumor Growth in Murine Models of Breast Adenocarcinoma," was published in the May issue of Clinical Cancer Research, a journal of the American Association for Cancer Research.

DNA constraints control structure of attached macromolecules

 

CHAMPAIGN, Ill. -- A new method for manipulating macromolecules has been developed by researchers at the University of Illinois at Urbana-Champaign. The technique uses double-stranded DNA to direct the behavior of other molecules.

In previous DNA nanotechnology efforts, duplex DNA has been used as a static lattice to construct geometrical objects in three dimensions. Instead of manipulating DNA alone into such shapes, the researchers are using DNA to control the folding and resulting structure of RNA. Eventually, they envision building supramolecular machines whose inner workings are governed by twisted strands of DNA.

In a paper that has been accepted for publication in the Journal of the American Chemical Society, and posted on its Web site, Silverman and graduate student Chandrasekhar Miduturu begin with a piece of unfolded RNA. Through specific chemical reactions, they attach two strands of DNA, each resembling one side of a ladder.

Adsorbent materials for the storage of hydrogen

A research team from the Public University of Navarra has started a study of the design and development of absorbent materials that enable the storage of hydrogen, a clean fuel that can be used as an alternative to those derived from fossil fuels, such as petrol and diesel. The storage of this element is, in fact, a key process in the change over from internal combustion engines – contaminating and not very efficient, to cars with hydrogen fuel cells.

The project, entitled, Development of materials for storage of hydrogen by means of physical adsorption.

At present, hydrogen production “is not a problem”. For some years now, hydrogen has been obtained by means of catalytic reforming or by the electrolysis of water. However, the question hanging over the use of hydrogen as a fuel is its generation or storage in the quantities required for a means of transport and without it being dangerous – as we are dealing with a highly inflammable gas. Under normal conditions hydrogen is in a gaseous state and thus has to be kept under high pressure or, if we wish to reduce the pressure, the storage temperature has to be lowered. These two circumstances give rise to technological difficulties, apart from the added safety ones...read the wave

UF'S RECORD-SETTING NEW CHIP HAS POTENTIAL FOR BIOTERRORISM DETECTION

 

GAINESVILLE, Fla. --- Researchers have built a world-record high frequency chip using a common type of semiconductor, an advance that could lead to inexpensive systems for detecting hidden weapons, and chemical and biological agents.

Engineers at the University of Florida and United Micro Electronics Corp., a Taiwan- based semiconductor manufacturer, announced late last week they had built the 105 gigahertz circuit using widespread complementary metal oxide semiconductor, or CMOS, technology – the same technology found in most of the chips in ubiquitous personal computers and handheld electronic devices.

The previous record for CMOS circuits was 103 gigahertz, reported in February of last year, but that circuit consumed four times more power than the newly announced circuit and was built using a more advanced technology. Gigahertz is a measurement of frequency, with one gigahertz equaling 1 billion cycles per second, or a wave repeating its motion 1 billion times in one second...read the wave

CBEN: Buckyball Aggregates are Soluble, Antibacterial

Research Offers Clues About C60 Behavior in Natural Environments

 

HOUSTON, In some of the first research to probe how buckyballs will interact with natural ecosystems, Rice University¹s Center for Biological and Environmental Nanotechnology finds that the molecules spontaneously clump together upon contact with water, forming nanoparticles that are both soluble and toxic to bacteria.

The research challenges conventional wisdom: since buckyballs are notoriously insoluble by themselves, most scientists had assumed they would remain insoluble in nature. The findings also raise questions about how the buckyball aggregates ­ dubbed nano-C60 ­ will interact with other particles and living things in natural ecosystems.

The findings appear in the June 1 issue of the journal Environmental Science & Technology.

New Material Could Improve Fabrication of Nanoscale Components

 

A team of chemists at Penn State has developed a new type of ultrathin film, which has unusual properties that could improve the fabrication of increasingly smaller and more intricate electronic and sensing devices. The material, a single layer made from spherical cages of carbon atoms, could enable more precise patterning of such devices with a wider range of molecular components than now is possible with conventional self-assembled monolayers. The research is published in the current issue of the Journal of the American Chemical Society .

The molecules that make up the material have larger spaces and weaker connections between them than do components of conventional self-assembled monolayers. "The bonding and structural characteristics of this monolayer give us the opportunity to replace its molecules with different molecules very easily, which opens up lots of possibilities for both directed patterning and self-assembled patterning," says Paul S.

The team reports (1) (in Tetrahedron: Asymmetry ) the successful synthesis of gold nanoparticles featuring covalently bonded, immunogenic oligosaccharides from the Ley determinant, which is associated with various carcinomas including colon, liver, prostate and ovarian.

The methodology ensures the preparation of functional, three-dimensional "glyco-stealth coronas" of immunogenic carbohydrate and peptide ligands on discreet, stable and water-soluble gold nanoparticles. To ensure maximum antigenicity, carbohydrate and peptide epitopes are linked covalently to the gold nanoparticle core by "spacers" of defined length. In this way a high surface density of the antigens is presented on the shell of the gold nanoparticles.

Inner Structure of Cells Behaves Much as Molten Glass

Finding may impact understanding of mechanical facets of many diseases

 

Boston, MA - An international team led by Jeffrey J.

These findings appear in advance online from the July, 2005 issue of Nature Materials ( http://www.nature.com/nmat/index.html ).

Physicists clarify exotic force, but no 'Theory of Everything' yet

A New Model of Quantum Dots: Rethinking the Electronics

The optics and electronics of these semiconductor nanocrystals are dramatically different from the same materials in bulk. But it turns out that one of the most important electronic properties of quantum dots has been misunderstood for over a decade.

Theorists at the Department of Energy's Lawrence Berkeley National Laboratory have shown that a quantum dot's dielectric function (a term indicating how charge responds to an electric field) does not depend on its band gap, as researchers long believed. On the contrary, the dielectric function of a quantum dot, measured on the microscopic scale, is virtually the same as that of the bulk material -- except near the dot's surface....read the wave

Low-cost polymer nanostructure replicas

 

At the University Twente, Laura Vogelaar is developing a new technique for creating small structures in plastic, giving way to new possibilities for many applications. For example, medicine could use their biodegradable polymer matrices to grow human tissue e.g. for bone replacement.

It seemed so obvious, yet the University of Twente was the first to have the brilliant idea: making microstructured surfaces by simply smearing a polymer solution onto a silicon mould and having it solidify rapidly. Up till then, often polymers were pressed in a mould consisting of a kind of hot 'clay' , with the risk of getting stuck and not coming out at one piece - just think of the freshly baked cake from you kitchen stove.

Making replicas with the help of a mould is a commonly used process in industry. Copies from master CD's for example, are made by pressing heated plastic in a mould. "Hot embossing" this technique is called...read the wave

China tops the world in nano-papers

 

News from the 2005 China International Conference on Nanoscience and Technology (China Nano 2005) held on June 9 says that by December 2004 China has had more than 800 companies engaged in trade in nano-technology and about a hundred nano-technology research institutes. More than ten projects such as for making Li cells, solar cells, textiles and environment-friendly interior paints have been commercialized.

According to academician Bai Chunli, director of the National Center for Nanoscience and Nanotechnology, China is one of the first in the world to launch research on nanotechnology. It has had a research team of more than 3,000 people and achieved a series of innovative research results. China has become an important force in the world's nano-tech research. From January to October 2004 China topped the world in terms of SCI nano-tech papers.

China has put a total of 830 million yuan into the R&D of nanoscience and nanotechnology. The central government has started a major program on nano-materials and Microelectromechanical System (MEMS).

Experts suggest that to develop nanotechnology in the future China should first step up constructing public technological platform for nanotechnology; conform research resources, promote the crossing and merging of different disciplines and the consolidation of goals of different disciplines as well as technological integration and innovation. China should also regularize commercialization of nanotechnology through enacting nano-product standards and certificating nanotechnology so as to improve the international competitiveness of Chinese nano-tech companies.By People's Daily Online

Golden balls by molecular painting

 

Superparamagnetic colloids with independently controllable magnetic and optical properties have been made by researchers from Universities in Germany and Spain. Marina Spasova from the University of Duisburg-Essen, describes their technique as ‘…decorating optically active colloids with a magnetic moment..''(Journal of Materials Chemistry, April 2005). The magnetic moment gives a simple mechanism for self-assembly of the spherical colloid particles by applying an external magnetic field. The materials formed make ideal candidates for photonic band gap materials (ie materials that exclude the passage of photons in a certain wavelength band just as semiconductors exclude the movement of electrons in a certain energy band).

Before being ‘painted' with the nanoparticles the negatively charged polystyrene surfaces are ‘primed'with three layers of PDADDMAC [poly(diallyldimethylammonium chloride)]/PSS[poly(sodium 4-styrenesulfonate)]/PPDDADMAC. This gives a uniform positive covering to the surface. The use of the negatively charged magnetite and gold nanoparticles ensures that electrostatic attraction will lead to even deposition on the microspheres. Excess magnetite or gold can be removed from the aqueous suspension by centrifugation/washing cycles. New layers of PDADMAC/PSS/PDAADMAC are adsorbed to the surface before deposition of each nanoparticle layer to give the correctly charged surface. Each magnetite layer was found to be 25±5nm thick, corresponding to 2-3 monolayers with gold layers about 20±5nm thick corresponding roughly to a monolayer (about 20nm)...read the wave

Pitt researchers see electron waves in motion for first time

New imaging technique—a trillion times faster than conventional techniques—advances field of plasmonics, could lead to better semiconductors

 

Both the ancient art of stained glass and the cutting-edge field of plasmonics rely on the oscillation of electrons in nanosized metal particles. When light shines on such particles, it excites the electromagnetic fields on the metal's surface, known as "surface plasmons," and causes its electrons to oscillate in waves--producing the rich hues of stained glass.

But because electrons move nearly as fast as light, those oscillations have been difficult to observe and had never before been seen in motion. Now, in a paper published in the current issue of the journal Nano Letters, Pitt researchers have demonstrated a microscopy technique that allows the movement of the plasmons to be seen for the first time, at a resolution a trillion times better than conventional techniques...read the wave

Quantum dots prove to be a faster, more sensitive method for detecting respiratory viral infections

 

In what may be one of the first medical uses of nanotechnology, a chemist and a doctor who specializes in infectious childhood diseases have joined forces to create an early detection method for a respiratory virus that is the most common cause of hospitalization among children under five.

Respiratory syncytial virus (RSV) sends about 120,000 children to the hospital in the United States each year. Although it is only life-threatening in one case out of every 100, it infects virtually all children by the time they are five. Few children in the U.S. die from RSV, but it also attacks the elderly, causing some 17,000 to 18,000 deaths annually. Individuals with impaired immune systems are another highly susceptible group. Worldwide, the virus causes about one million deaths annually.

Current methods of detecting the virus can take from two to six days, postponing effective treatment. The new, high-tech method uses multi-colored, microscopic fluorescent beads, called quantum dots, which bind to molecular structures that are unique to the virus's coat and the cells that it infects. In a paper appearing in the June issue of the journal Nanoletters , the Vanderbilt researchers report that not only can a quantum dot system detect the presence of particles of the respiratory syncytial virus (RSV) in a matter of hours, rather than the two to five days required by current tests, but it is also more sensitive, allowing it to detect the virus earlier in the course of an infection....read the wave

Nanotechnology Partnerships, Connections Spur Innovation for Fluid Control Industries

 

Bellingham, WA (PRWEB via PR Web Direct )–- Microstaq founders Steve Booth and Jeff Chance knew a lot about automotive systems and little about microtechnology when they set out eight years ago to create a new business making a better flow control valve. Having worked in business development and sales for a large automotive company, the two were in a position to improve on the manufacturing of traditional mechanical valves that run various automotive flow control systems and they knew how to sell it.

They were seeking a manufacturer for their valve when they met Bob Mehalso, an internationally recognized expert in nanotechnology and microsystems. Mehalso is a consultant in micro-electro-mechanical systems, or MEMS technology, and a man with many contacts in the micro-manufacturing industry. His innovative approaches to commercializing nanosystems have lead to products such as ink-jet print heads and fuel-injection nozzles.

Unweaving amyloid fibers to solve prion puzzles

 

Amyloid fibers are best known as the plaque that gunks up neurons in people with neurodegenerative illnesses such as Alzheimer's and Creutzfeldt-Jacob disease--the human analog of mad cow disease. But even though amyloids are common and implicated in a host of conditions, researchers haven't been able to identify their precise molecular structures. Conventional techniques used to image proteins, such as X-ray crystallography and nuclear magnetic resonance imaging, don't work with fibrous structures such as amyloids. And scientists depend on these high resolution images of molecules in order to study their function.

Now, researchers have found a way to work around these limitations, illuminating the configuration of these sometimes pernicious molecules. And even though this work was done in yeast, the results provide hints as to why mad-cow type diseases tend to have a difficult time jumping species.

"These findings give us some fundamental insights in how amyloid fibers form," says Whitehead Member Susan Lindquist, lead scientist in the research team whose results will be published in the June 9 issue of the journal Nature. "They solve the important problem of identifying the intermolecular contacts that hold the amyloid fiber together."..read the wave

Mit Hilfe von Computerberechnungen ist es Wissenschaftlern des Max-Planck-Instituts für Mikrostrukturphysik und der Martin-Luther-Universität in Halle zum ersten Mal gelungen, die bisher rätselhaften Vorgänge in "Quantenkäfigen" im Detail nachzuvollziehen. Diese Gebilde werden in einzelnen Schritten aus wenigen Dutzend Atomen künstlich in Form einer Ellipse - einer ovalen Miniaturschachtel - zusammengesetzt und sind nur wenige Nanometer (= Millionstel Millimeter) klein. Platziert man einzelne magnetische Atome in das Innere, lässt sich - das zeigen die Berechnungen - deren Kopplung gezielt so verändern, dass sie sich entweder "ferromagnetisch" (parallele magnetische Momente) oder "antiferromagnetisch" (entgegengesetzt gerichtete magnetische Momente) einstellen.

Dr Werner Hofer, from the University's Surface Science Research Centre, is one of an international team of scientists who have created a prototype that demonstrates a single charged atom on a silicon surface can regulate the conductivity of a nearby molecule. Computers and other technology based on this concept would require much less energy to power, would produce much less heat, and run much faster.

Currently, most electronic devices are based on silicon. There is, however, a limit to how many transistors can be packed into a given volume of silicon as the currents in these transistors are high and can overheat. By miniaturizing a transistor, the time during which an electron can pass through it is reduced and therefore the device can be operated with much higher frequencies and take up much less space...read the wave

Researchers demonstrate use of gold nanoparticles for cancer detection

 

Binding gold nanoparticles to a specific antibody for cancer cells could make cancer detection much easier, say medical researchers from the University of California, San Francisco and Georgia Institute of Technology .

The researchers are a father and son, working together on opposite coasts. Their study findings are reported in a recent edition (May 11) of the journal Nano Letters , published by the American Chemical Society.

Principal author is Ivan El-Sayed , MD, assistant professor of otolaryngology at UCSF Medical Center , who conducted the study with his father, Mostafa El-Sayed , PhD, director of the Laser Dynamics Laboratory and chemistry professor at Georgia Tech.

"Gold nanoparticles are very good at scattering and absorbing light," said Mostafa. "We wanted to see if we could harness that scattering property in a living cell to make cancer detection easier. So far, the results are extremely promising."

Many cancer cells have a protein, known as epidermal growth factor receptor (EFGR), all over their surface, while healthy cells typically do not express the protein as strongly. By conjugating, or binding, the gold nanoparticles to an antibody for EFGR, suitably named anti-EFGR, the researchers were able to get the nanoparticles to attach themselves to the cancer cells...read the wave

NIST photon detectors have record efficiency

 

Sensors that detect and count single photons, the smallest quantities of light, with 88 percent efficiency have been demonstrated by physicists at the National Institute of Standard and Technology (NIST). This record efficiency is an important step toward making reliable single photon detectors for use in practical quantum cryptography systems, the most secure method known for ensuring the privacy of a communications channel.

Described in the June issue of Physical Review A, Rapid Communications,* the NIST detectors are composed of a small square of tungsten film, 25 by 25 micrometers and 20 nanometers thick, chilled to about 110 milliKelvin, the transition temperature between normal conductivity and superconductivity. When a fiber-optic line delivers a photon to the tungsten film, the temperature rises and results in an increase in electrical resistance. The change in temperature is proportional to the photon energy, allowing the sensor to determine the number of photons in a pulse of monochromatic light....read the wave

Nanotechnology Aims to Improve Drug Synthesis

 

To Cornell University chemist Tyler McQuade, Ph.D., one fact about the way pharmaceuticals are made worries him. "For every kilogram of pure drug molecule that gets made, the pharmaceutical industry generates 25 to 100 kilograms of waste, and since most of that waste originally comes from oil refining, I'm concerned that the cost of making life-saving pharmaceuticals could soar with the price of oil.

Advance Nanotech Subsidiary Announces New Patent Application for Programing Implantable and Body-Worn Biosensors

 

Bio-Nano Sensium Technologies, a subsidiary of Advance Nanotech, Inc., (OTC BB:AVNA.OB - News), today announced a new patent application that will reduce the cost and complexity of programming wireless biosensors. Wireless biosensors are increasingly seen as a desirable treatment for a range of chronic conditions including diabetes, cardiac conditions and asthma.

Bio-Nano Sensium Technologies has developed a simplified, more effective method for the calibration of wireless biosensors. Calibration is the procedure that ensures the accuracy of a sensor's data output. All biosensors must be initially calibrated when they are implanted or applied to the skin, and periodically afterwards, to correct the tendency for output to "drift" over time. Traditionally, sensor calibration was conducted offline, using an external process that was expensive and time consuming. Bio-Nano Sensium's new process enables automatic biosensor calibration immediately upon insertion, eliminating the expense and inconvenience of off-line calibration procedures...read the wave

Backing from AMRC Benefits Promising High-Tech Startups in Texas

 

Austin, TX (1 June 2005) - Four up-and-coming high-tech companies that started in Texas are getting technological and financial boosts from the Advanced Materials Research Center (AMRC), the joint advanced R&D effort involving SEMATECH and Texas universities.

The AMRC beneficiaries include innovators in leading-edge lithography, next-generation lighting, organic RFID systems, optical interconnects, wireless networks, and nanomaterials. Each is receiving technology or support from the AMRC, which was established in 2004 to develop new materials and nanostructures for semiconductors, and to explore opportunities for nanotechnology, biotechnology, and other emerging technologies.

"One of our primary aims in forming the AMRC is to commercialize new technology in ways that can benefit the people of Texas, by helping create the industries and jobs of the future," said Sanjay Banerjee, technology coordinator for the AMRC and a key educator in the College of Engineering at The University of Texas at Austin. "Here, we have the first fruits of that effort - four companies that are receiving significant knowledge or support for their commercially feasible innovations."...read the wave

Japan's Matsushita to sell nanotech hair dryer

 

TOKYO - Matsushita Electric Industrial Co has announced it will begin sales of a new type of hair dryer that has nanotechnology functions starting June 21.

While drying, the product will provide the hair with moisture by blowing nanometer-scale ions. It will sell for about 18,000 yen (US$165), and the firm plans to produce 9,000 units a month.

Matsushita included in the hair dryer its own "nanoe ion" generator equipment used in its air purification products.

The dryer's tank is filled with special water or a commercially available purified water. With the application of high voltage, small droplets with a roughly 18 nanometer radius are generated. These are blown on the hair to give it moisture...read the wave
