Peptide based biosensors

This review provides an overview of the various types of (bio)sensors based on peptides for their analytical use, along with significant advances over the last several years in related technologies. So, it will be described: i) principles in biosensing using peptides ii) aspects of fabrication in the perspective of (bio)sensing applications iii) potential of electrochemical, electrochemiluminescence, photoelectrochemical, and optical (bio)sensors for the determination of target analytes within sub-nanomolar range also discussing the main problems in (bio)sensing iv) multiplex electrochemical and optical (bio)sensors, both with and without labels. v) Latest developments in the applications of (bio)sensors methods for detection of important analytes in real samples. vi) the application of nanotechnology and microfluidic technology on peptide based biosensing.
