Abstract

Microbial fuel cells (MFCs) are being studied as a biosensor for a wide gamut of applications. Currently, since the power generated by an MFC is too low to power any practical devices, it is pertinent to use MFC as a sensor for the accurate and simple measurement of various analytes. The present chapter deals with the various upcoming applications of the MFC technology in the field of sensing with an emphasis on Biochemical Oxygen Demand (BOD) bio-sensing. The application of MFCs as BOD biosensor is one of the most widely studied fields followed by the volatile fatty acid sensing and toxicity sensing. Figure 20.1 depicts various novel applications of MFC as biosensor from the literature.
