As a new analysis and detection technology combining microbial water treatment and electrochemical sensing, microbial fuel cell(MFC) sensor has the characteristics of self-sustainable monitoring without additional power supply and signal conversion device. Thus, it shows great application potential during online water quality monitoring. This review starts with the working principle of MFC sensor, mainly introduced the research progress of this technology in water toxicant detection field, and focused on the advantages and disadvantages of single/two-chamber reactor configuration and constant external resistance(CER)/constant anode potential(CAP) operation mode. Moreover, the optimal environmental conditions such as dissolved oxygen(DO), solution temperature and pH value for the normal operation of MFC sensors are summarized. And then, those important indices reflect the sensitivity and stability of sensor, such as response time, detection limit, recovery rate and signal reproducibility are focused on, and the positive influence of optimizing sensor configuration and operating mode, reducing hydraulic retention time(HRT), on promoting the aforementioned indicators are also discussed, which is aiming to obtaining effective methods to promote toxicant detection property of MFC sensors. Finally, the prospective strategies and development direction of this technology in the field of water quality monitoring are prospected.
