Surface acoustic wave (SAW) biosensors possess advantages of high efficiency, low cost and label free detection, and have potential applications in clinical diagnostics. However, it is a great challenge for SAW biosensors to detect small concentrations of biomarkers in clinical sample. Nanomaterials have been widely used in bioanalysis techniques to fabricate highly sensitive biosensors. In this paper,...
Temperature has great influences on the surface acoustic wave (SAW) biosensors. Different substrates were tested and the methods for improving the temperature performance of the SAW biosensors were discussed here. The effects of temperature on the SAW sensors mainly result from the temperature coefficient of the SAW device and the oscillating circuit. To eliminate the impact of environment, a twin...
