OAK RIDGE, Tenn., May 24, 2005 — A device that could create custom-tailored
medical compounds faster than ever before is one of the first projects launched
under the new Center for Nanophase Materials Science at Oak Ridge National Laboratory.
Project director Joseph Matteo, founder and CEO
of the local research firm NanoTek, is building a
small, microfluidic machine to quickly and reliably
synthesize drugs, medicines, diagnostic imaging agents
and other compounds.
His work is part of the CNMS Jump Start Program,
which gives selected nanoscience projects access
to ORNL research facilities and staff before the
center begins full operation in October.
The program includes more than 75 research proposals,
all of which are evaluated by an external scientific
review committee, selected for scientific merit and
quality, and will be published in the scientific
press.
"Being local and one of the first commercial clients
of the CNMS, I feel added responsibility to make
this a success," Matteo said. "There is a huge amount
of support from the community. The road is by no
means easy, but this region has a unique opportunity
in having the first of five of these centers in the
country, and we are trying to take advantage of it."
CNMS is the first of five Nanoscale Science Research
Centers being built by the Department of Energy.
The center will be housed in an 80,000-square-foot
building on Chestnut Ridge beside the Spallation
Neutron Source.
Assisting Matteo will be ORNL researchers Timothy
McKnight and Gomez Wright, of Engineering Science
and Technology Division and Michael Simpson of the
Condensed Matter Sciences Division. Simpson is a
CNMS Theme Leader, and a joint ORNL-University of
Tennessee scientist.
Matteo's device uses ORNL developed technology to
manipulate ions in a stream of solution. Potential
commercial applications can be found in industry,
medicine, and even bio-threat detection. The high-speed,
low-volume characteristics are ideally suited to
demanding applications such as individualized medicines
and drugs tailored to each patients needs; short-order
manufacturing of drugs/chemicals with a short shelf
life; and a better way to make short-lived radioactive
compounds for medical diagnostic imaging technology
such as positron emission tomography (PET).
His ideas to enhance the chemistry of drug development
offer many advantages over commercially available
technology. While current methods can rapidly explore
thousands of variants of a compound to achieve a
certain solution, their parallel high-volume nature
is not information driven. A closed-loop, information
driven system offers a serial or sequential discovery
method and promises a more "intelligent" drug-making
process, Matteo said.
"Combinatorial or parallel processing chemistry
can do a process thousands of times to get the right
answer, but its like casting a large net to capture
a small solution," Matteo said. "If you've pointed
the device in the wrong direction, you'll need to
cast again.
"With a serial approach, if you can learn something
every step of the way, you can very efficiently find
a solution. The challenge is to build more and more
intelligence into a closed-loop discovery machine
that synthesizes the drug, tests it, gets information
along the way, feeds it back, and optimizes the drug
to the desired properties."
The concept presents the potential for "point of
use" synthesis of drugs and a new era of personalized
medicine, where patients visit the doctor, have tests
done, and receive medicines formulated especially
for them in minutes.
Matteo, a former division director for CTI, a Knoxville
molecular imaging firm, cited Tech 2020, an Oak Ridge
regional economic development organization, and ORNL's
Technology Transfer directorate for encouraging his
project. He said establishment of the CNMS was the
driver that inspired him to pursue his ideas for
nanotechnology applications.
"I had a fundamental interest in nanotechnology
for many years. Once I found an application and learned
more about it, I became really intrigued, but the
real launching pad for me deciding to do this was
the CNMS facility being built here," Matteo said. "Certainly,
without that I would not have done this. It is absolutely
the cornerstone."
Jump Start participants are in Oak Ridge this week
for the inaugural CNMS User Meeting, which seeks
to help prospective users learn about the center's
capabilities and meet ORNL scientists to discuss
user research proposals. For more information, go
