Advance Nanotech Subsidiary Announces Patent for New Implantable and Body-Worn Biosensors; New Technology to Improve Treatment for a Wide Range of Chronic Conditions

NEW YORK CITY--(BUSINESS WIRE)--May 11, 2005--Bio-Nano Sensium Technologies, a subsidiary of Advance Nanotech, Inc., (OTC BB:AVNA.OB), today announced a significant step forward for 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 filed for a patent on a new technology that will automatically bring imbedded biosensors into conformance with international frequency and operating requirements. Until now, patients with embedded or worn wireless biosensors had difficulty traveling internationally. Frequency and operating regulations differ from nation to nation, and the results of transmitting and receiving wireless signals on a prohibited spectrum range from irritation to fatal consequences for the person using the biosensor. Bio-Nano Sensium Technologies is a joint venture between Advance Nanotech, Inc. and Toumaz Technology Ltd., a UK-based developer of advanced RF, analog and mixed signal semiconductors.

“The technology we are patenting is a huge step forward in our goal of developing biosensor platforms that have real and immediate impact in the treatment of chronic conditions”

"Bio-Nano Sensium Technologies is advancing science, and ensuring the comfort of patients of chronic illness," said Stephanie Interbartolo, SVP of Business Development of Advance Nanotech. "The company has removed a significant barrier to the widespread use of wireless devices for medical applications, bringing down costs of ownership and facilitating practical new treatments."

This latest patent is the first filed by Bio-Nano Sensium in the past year in its own name with a plan to file additional patents by year's end. Bio-Nano Sensium also has exclusive access to Toumaz Technology's patent portfolio in the bio-nano field. The increasing number of patents reflects the company's rapid progress in its scientific discovery process toward offering the market's most advanced wireless biosensors.

"The technology we are patenting is a huge step forward in our goal of developing biosensor platforms that have real and immediate impact in the treatment of chronic conditions," said Keith Errey, CEO of Toumaz Technology. "We have worked diligently over the past four years to develop a patented, low-power platform technology to leverage for this kind of important commercial application. It is gratifying to see us come a large step closer to realizing this goal."
