Role of Silk in Recent Advances of the Biosensors: A Mini-Review

Abstract

A biosensor is a kind of analytical device that is composed of a biological recognition element associated with a mechanism for stopping and interpreting the signal obtained from the interaction between the analyte and the analytical instrument. More importantly, silk is one of the natural biocompatible substances with incredible strength and flexibility that is widely applied in various applications. Its excellent mechanical properties and versatility have made it an ideal choice for fabricating biosensors, especially electrochemical ones. Therefore, attention to silk-based biosensors increased incredibly over the recent decades, and these biosensors have been deployed as an indispensable research area in the scientific society. Accordingly, this mini-review paper comprehensively investigates the role of silk in the recent advances in biosensors.
