Lightweight Biosensor Badge to Monitor Environmental Organophosphates

"The US Joint Services, Federal Agencies, and state and local First Responders have expressed dissatisfaction with currently employed organophosphate (OP) sensors. They have identified the need for a new generation of sensors that is small, light-weight,and easy to use while being capable of extended operations in rugged environments. Advanced Sensor Technologies proposes to address these issues with its miniaturized, organophosphate alert device (MOPAD), a device that not only meets the stated objectivesbut is also capable of identifying the particular conformation of OP in the environment and alerting the wearer of its presence.The MOPAD takes advantage of the phenomenon that OP's effect cholinesterase enzyme activity. By continually monitoring cholinesterase reaction kinetics, the particular type and concentration of the OP can be determined. Unlike current sensors, the MOPADwill be capable of monitoring OPs in non-vapor environments, i.e. in soil samples, liquids, solids, etc., via absorption into the contained test medium.The proposed technology will see widespread application in both civilian and military markets. Beyond the set of users identified in the solicitation, this device could also be used by farmers (to monitor exposure to fertilizer), and individuals thatapply pesticides and/or lawn fertilizers, etc. The proposed technology will see widespread application in both civilian and military markets.
