Bioelectrochemical Systems as a Multipurpose Biosensing Tool: Present Perspective and Future Outlook

Abstract Microbial bioelectrocatalysis, the process of utilizing an intact microorganism for catalyzing redox reactions, has been rapidly expanding over the last 15 years. Although microbial bioelectrocatalysis has been primarily studied for power generation and wastewater treatment, this Minireview will focus on the use of bioelectrochemical systems (BESs) for biosensing applications. This will include sensors for water quality, corrosion, and toxic shock. We will also discuss the transition of BESs to photo‐BESs and discuss their recent applications in sensing. Finally, we will discuss the future outlook for microbial bioelectrocatalysis for biosensing applications.
