Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

Advanced Materials Technologies, Volume 10, Issue 20, October 20, 2025.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.
