Detection of trichinosis using TSM immunosensor

A thickness shear mode (TSM) immunosensor was developed for detection of trichinosis in this paper; antibody was immobilized on to the surface of a quartz crystal precoated with styrene–butadiene–styrene (SBS) copolymer. The sensor interacted sensitively with trichinosis antigen and produced a change in resonant frequency of the quartz crystal. The fractal analysis was proposed for both processes. This method was applied to the detection of some samples with different amount antigen sera diluted by phosphate buffered saline (PBS) and good results were obtained.
