Phage-Displayed Epitopes as Bioreceptors for Biosensors

“Phage display” is a powerful technique that allows expression of peptides or proteins on the phage surface. Exploitation of phage display technology will lead to isolation and production of a broad range of binders with predefined specificities. Emergent technologies based on phage display will benefit diagnostics by producing molecules that are otherwise unobtainable through traditional approaches. Exploitation of the advantages of phage display systems together with the ongoing development in the biosensor field would lead to revolutionary diagnostic devices. This chapter will focus on phage biology, the advantage of phage display, and its applications as epitope bioreceptors in biosensor use.
