We are pleased to announce the Special Issue of Biosensors (IF=3.2) on “Microbial Fuel Cell – based biosensors”, edited by Dr. Grzegorz Pasternak.
The application of microbial fuel cell (MFC) technology in biosensors is gaining increasing interest from the scientific community. MFCs offer unique and attractive features of low cost, fast response time, ease of signal measurement and interpretation, and long-term operation due to the regeneration of electroactive bacteria, which makes them ideal for environmental applications.
Following the first experiments on biological oxygen demand measurements, MFC biosensors have proven their capability for immediate measurement and monitoring of organic matter in various environments. These devices have also been demonstrated to work as early warning systems through the detection of toxic compounds. Furthermore, due to electricity generation, they can work in an entirely autonomous manner.
This exciting field spans several research areas, and further progress requires an interdisciplinary approach. Several challenges are still waiting to be addressed in either improving or extending upon existing concepts within the area. Among them, stability in various environmental conditions, the selectivity of microbial strains and communities towards specific substrates, and MFC performance are avenues that remain open for exploration.
The SI is devoted to progress in the development of microbial fuel cell-based biosensors, covering both fundamental and applied aspects towards their practical implementation.
