STEALTH: A New Chem/Bio Sensor Based on Differential Fluorescence from Molecularly Imprinted Polymers

Sentor Technologies Inc. proposes to develop and demonstrate a new STEALTH chem/bio sensor technology based on differential fluorescence from molecularly imprinted polymers. In the phase I project period, the feasibility of both the STEALTH sensor as well as an integrated vapor sampler/concentrator based on the charged nanodroplets produced from an electrospray source was successfully demonstrated. The vapor sampler/concentrator was invented by Nobel prize winning Chemist Dr. John Fenn, who is the University PI on this proposal. The proposed STEALTH sensor utilizes a patent-pending sensing strategy that eliminates the need for spectroscopic analysis, thereby greatly reducing the sensor hardware and power requirements. The phase II project will culminate in the development and demonstration of a fully integrated sensor prototype with a combination of performance parameters far surpassing any existing technology.
