Reviewing the use of chitosan and polydopamine for electrochemical sensing

Biopolymers possess highly favorable properties for electrochemical biosensing such as their inherent biocompatibility, inexpensive nature, and strong interfacial adhesion. In this mini-review, we will focus on chitosan polydopamine, two of the most commonly used biopolymers, sensing applications. Chitosan is a polysaccharide that exhibits high chemical resistance, offers straightforward modification cross-linking, possesses antibacterial mucoadhesion. Polydopamine has benefit universal adhesion, in addition to ability form self-assembled structures. We demonstrate how unique structural features these biopolymers can be range platforms.
