NEW YORK --(Business Wire)-- Nov. 4, 2005 -- Owlstone Nanotech, Inc., a pioneer in the commercialization of nanotechnology-based chemical detection products, today announced a beta testing program with Kidde, the global fire and safety group. The Owlstone Sensor, a nano-fabricated chemical detection system, will be tested for suitability in the next generation of its safety detection, prevention and protection systems. Owlstone Nanotech is a subsidiary of Advance Nanotech, Inc., (OTC BB:AVNA.OB - News). Kidde is part of UTC Fire & Security, a business unit of United Technologies Corp. (NYSE:UTX).

Owlstone is developing a revolutionary micro-machined gas sensor, which, with its associated electronics and software, provides what is in effect an analytical instrument on a chip, programmable for a range of analytes. The technology holds significant promise for the cost-effective detection of volatile organic compounds related to pre-combustion fire events and indoor air quality monitoring. These are currently very difficult to detect and differentiate in an inexpensive manner using existing chemical sensors.

"Our mission is to make the world a safer place. Owlstone is developing miniaturized chemical detection sensors that quickly and accurately identify trace elements of toxins, contaminants and chemical agents - something that may play an integral part in making the world safer," said Max Allsworth, senior research physicist, Kidde. "We are very excited to investigate how the Owlstone Sensor may help Kidde bring new functionality to its industry-leading set of fire detection products."

Owlstone Nanotech has used leading-edge micro- and nano- fabrication techniques to create a chemical detection system one hundred times smaller and a thousand times cheaper than existing technology. Owlstone Nanotech partners with market leaders to integrate its technology into a wide range of commercial applications to allow the efficient and accurate detection of various chemical agents including contaminants, chemical warfare agents and potentially harmful gases. This revolutionary technology will help to redefine chemical detection systems, opening the door to new and innovative products across a wide-range of industries.

"People trust Kidde to provide the most advanced systems for safety detection, prevention and protection; the company is dedicated to protecting people and assets from everyday hazards and danger," said Paul Boyle, president and co-founder, Owlstone Nanotech. "We believe that the Owlstone Sensor will enable Kidde to deliver an even more powerful generation of detection systems that alert people to fires, fumes and other dangers at the earliest possible moment, reducing the number of injuries and deaths caused by fires."
