Abstract

It is proposed to investigate the utility of soliton devices (SSD) as the basis for a novel range of high sensitivity, low noise, biosensors. Solitons are robust pulses whose shape is defined by sech or tanh functions that can be propagated in optical, acoustic and magnetic dispersive non-linear materials. Work will concentrate on acoustic and magnetic thin film devices in which the surface interrogative evanescent fields and large powers of surface solitons can be exploited in SAW type transducers to monitor the effects of liquid and adsorbed biological layers on the distortion of the soliton. Instrumentation comprising an RF Programmable Pulse Synthesiser and pulse detector/analyser will be constructed to monitor the internal phase angle, the time taken for the distorted soliton to return to the original phase angle or the propagation time of the surface soliton. The devices will be investigated theoretically and confirmed with appropriate experimental systems of biological relevance.
