The Piezoelectric Biosensors: Principles and Applications, a Review

Piezoelectric materials have broad use in many technological applications and they are frequently embedded in electronic devices. In principle, the piezoelectric materials work as oscillators on piezoelectric effect principle and interaction with their surface is easily detectable hence they are well suitable for construction of biosensors recognizing affinity interactions. Assays based on reaction between antigen and antibody, two polynucleotide strains, aptamer and protein are well suited for such studies. The current review is focused on explaining of the piezoelectric biosensors function, data about available materials and examples of analytical applications. Survey of actual literature is provided here.
