Recent development of biofuel cell based self-powered biosensors

Abstract

Self-powered biosensors (SPBs) based on enzymatic biofuel cells (EFCs) and microbial fuel cells (MFCs) have attracted considerable attentions due to their obvious advantages such as simple configuration and ease of miniaturization, and the potential applications including clinic diagnosis, environmental monitoring and industrial process control, etc. In this review, we will summarize the recent advance in SPBs, focusing on the combination of EFC-SPBs as power sources with microelectronic and electrochromic devices, and the applications of MFC-based SPBs toward toxicity, chemical oxygen demand (COD), biochemical oxygen demand (BOD) and assimilable organic carbon (AOC). The efforts in, for example, boosting the energy, reducing cost, improving sensing performances in terms of sensitivity, accuracy and dynamic detection ranges, are discussed. Finally, future prospects in the development of MFC-based SPBs are presented.
