Bioelectrochemistry is a branch of science that studies the interactions between biological systems and electrical energy. It focuses on how living organisms, such as microorganisms and cells, can generate or utilize electrical currents through biochemical processes. This field has applications in areas like biofuel cells, which convert biological materials into electricity, and biosensors, which detect biological substances using electrical signals. Researchers in bioelectrochemistry explore various components, including enzymes, proteins, and membranes, to understand their roles in electron transfer and energy conversion. By harnessing these natural processes, scientists aim to develop sustainable energy solutions and improve medical diagnostics, making bioelectrochemistry a vital area of study in both environmental and health sciences.
