NanoSensors to Test E-Coli Biosensor Prototype

SANTA CLARA, CA /PRNewswire-FirstCall/ -- NanoSensors Inc., a nanotechnology development company that develops instruments and sensors to detect explosives and chemical and biological agents, announced that it has engaged a third-party contractor to manufacture units of a test version of its biosensor that will be used for third-party field testing. The company expects to receive delivery of the product units and commence testing during the first quarter of 2007 to obtain feedback on the performance of the biosensor. The product is based on the company's recently licensed nanoporous silicon-based biosensor technology to detect e-coli.

Although the company has not entered into testing agreements with third parties, the company is seeking to enroll six to ten users in its product testing program to subject the product design to simulated field conditions and to further assess the commercial viability of the current design. It is expected that the testing cycle will continue for a period of approximately three months, and the company intends to deploy the biosensors in a number of different testing conditions. After the testing period is complete, the company intends to incorporate user feedback into the product design to improve product functionality, as may be appropriate.

As previously announced, the proposed biosensor has been designed to consist of two core functional parts: a disposable housing unit in which the actual sensor device is mounted and a separate, external data acquisition unit. Based on this design, the disposable housing unit that contains the sensor transmits signals across electrical leads to the data acquisition unit, which accepts the output signal from the disposable housing unit and converts the signal to the appropriate format to display the results.

The first prototypes of the disposable housing unit and the data acquisition unit, including the software that converts the signal to the appropriate format to display the results, were completed earlier. The version of the biosensor that will be field tested is based on this product design.

"The development of our first biosensor product is on schedule," stated Dr. Ted Wong, the company's Chief Executive Officer. "We are starting the manufacture of a sufficient quantity of the disposable housing and data acquisition units now so that we can begin third-party testing of the product during the first quarter of 2007."
