Associate Professor Fengjun Yin published a technical paper “Pulse-opencircuit voltammetry: A novel method characterizes bioanode performance from microbe-electrode interfacial processes” in Biosensors and Bioelectronics Journal, doi.org/10.1016/j.bios.2022.114708. Bioanode is a basic component of bioelectrochemical systems. Survey of the process contribution to bioanode performance is pressingly required but it is still challenging. We propose a novel pulse-opencircuit voltammetry (POV) based on the electron flow pathways of microbe-electrode interfacial processes (MEIPs). A dual-cathode cell is designed to provide an experimental platform for ensuring precise data acquisition of bioanodes. This POV method enables to measure steady state polarization curves and ohmic potential loss curves and determine reaction resistance and ohmic resistance of biofilm. By means of these efforts, the proposed POV method is truly new and novel in terms of the technology form and its function in dissecting resistance distribution. We anticipate that this method together with the cell platform is accessible to users and has wide applications in bioanode construction and electroactive bacteria investigation.
