Mini Recap on Electricigens Biosensor and Their Applicability

Microbial fuel cell (MFC) is a favourable platform for continuous energy generation and monitoring wastewater treatment due to the electrochemically active microbes backing. Their considerable usage is in removing pollutants or toxic elements as a water softener in biosensors and formation of a few compounds. Despite various drawbacks predominantly including insufficient power supply, frequent noticeable growth in microbiological, chemical, and electrochemical viewpoints enables envisioning microbial fuel cell (MFC) biosensors as standard future analytical technology. This review summarizes the basic concepts, general understanding of the important associated terms with examples. The in situ online monitoring approach draws a special attention to the applicability part that majorly entails quantitative analysis of BOD and toxicants, along with additional benefits like monitoring specific microbial activity, MIC sensing, powering other sensors externally, antibiotic detection etc. Insight to modern strategies including miniaturization along with modified versions for better sensing is also provided. This paper briefs the microbial fuel cell (MFC)s as biosensors including the challenges and its future perspective.
