Biomapper for Gene Extraction

Triton Systems Inc. proposes to develop a new generation of SAW sensor coatings for the detection of TIMs. The proposed innovation employs a convenient, highly-controlled, and reproducible method to deposit conductive and nonconductive substrate coatingson SAW sensors. Since the proposed coatings can be used to operate on different transduction modes, they exhibit a high level of chemical Independence leading to enhanced selectivity and sensitivity. In Phase I, both conducting and non-conducting coatingswill be deposited on SAW crystals and their response to TIMs will be characterized. Systematic changes in coating properties will be examined in order to optimize their response characteristics. Since these coatings have high chemical flexibility,introduction of specific chemical functionalities to further increase their chemical diversity will also be attempted. In phase II, the most promising coatings identified in phase I will be used to construct and demonstrate a TIM sensor. We will alsoexamine the viability of using these conductive coatings in chemiresistor sensors.The proposed family of coatings will expand the collection of chemically independent interfaces available for SAW sensors. When incorporated in electronic noses, the proposedSAW sensors will find commercial applications in the food, beverage, and cosmetic industries. These sensor are also well suited to environmental pollution monitoring and industrial process monitoring.
