Ultra-low voltage electricity effectively damages and kills bacteria

Ultra-low voltage electricity is effective at killing bacteria because it causes membranes that surround bacteria to leak, according to a new study by University of Arkansas researchers. The research advances work to fight drug-resistant bacteria.
