In search of a high resolution sensing platform with the capability of wireless operation, we identified surface acoustic wave (SAW) devices as the most promising technology. In this review we discussed the working principles of SAW devices, their applications in sensing as well as the integration of nanostructures with SAW devices for achieving enhanced sensitivity. Future research challenges and benefits of nanostructured surface acoustic wave devices for biosensing applications were also addressed.
