Biological warfare sensor using molecularly imprinted polymers
Publication date: 2003
A sensor (10) for sensing biological warfare agents including a transducer and a molecularly imprinted polymer applied to a surface of the transducer. The molecularly imprinted polymer has at least one site capable of selectively binding a biological warfare agent formed therein. In one embodiment, the transducer can be a quartz microbalance including a quartz chip (14) to which the molecularly imprinted polymer (12) is applied, an oscillator (16), and a controller (18). The oscillator causes the quartz crystal chip to undergo oscillations of increasing amplitude so as to rupture any bonds between biological warfare agents and the molecularly imprinted polymer. The controller is capable of detecting such rupture events.
