Improved Field Biosensor for Organophosphates

Sensera Inc. proposes to develop ultra thin sensor coating fabrication technique for fast responding, selective and reusable sensors fabrication. This technique is easy to carryout, cheap and do not require expensive chemical conjugation steps. Theproposed sensor fabrication method take into account the challenges imposed by different sample matrices. The sensors can be made to operate in two signal transduction modes. We use two OP sensitive enzymes so that a wider array of organophosphates couldbe detected with certain degree of qualitative identification.In Phase 1 we will develop above sensor strips for organophosphate detection in air water and soil. They will be made to operate in two transduction modes. In phase I option we will develop sensors to detect agent degradation products in water as well asto further develop field identification capability. The proposed sensor strips are an economical way to check water courses and farmlands to ensure that pesticide usage does not result in ecological damage. They can be used to check contamination in food industry to check fresh produce. Most importantlythey can be used to check any accidental or deliberate contamination of bulic places and water sources.
