Piezoelectric biosensors: Recent advances and applications

Abstract

Modern biosensors developed with advanced microfabrication and signal processing techniques are becoming inexpensive, accurate, and reliable. Increasing miniaturization of biosensors leads to realization of complex analytical systems such as BioChemLab-on-a-Chip. This rapid progress in miniature devices and instrumentation development will significantly impact the practice of medical care as well as future advances in the chemical, pharmaceutical and environmental industries. In this paper piezoelectric biosensor technology and applications are presented and the challenges facing acoustic biosensor developers in the coming decade are discussed.
