| Abstract(in English) | Important application of acoustic wave sensors is to realize a biosensor. Since the acoustic wave sensor was proposed, many structures of the biosensor using acoustic sensors have been investigated. Recently, shear horizontal surface acoustic wave (SH-SAW) and Love wave are mainly used. Detection mechanism of a biosensor is mass loading effect on the sensing surface. Sensitivity of the mass loading effect depends on operating frequency and device structure. Especially, optimization of the sensor structure is important for realizing high sensitive biosensor. In this paper, we discuss optimum configuration of the biosensor based on numerical calculations and experiments. In the experiment, gold nanoparticles are deposited onto the sensor surface to compare the sensor sensitivity. The results indicate that the gold nanoparticle deposition method is effective method to compare the sensitivity of mass loading. Also, in this paper, it is mentioned that perturbation theory cannot apply for this purpose. |
