Antibacterial effects under different conditions. a, b Antibacterial rates of various samples a without charging and b during DC charging for 15 min. c, d Post-charging antibacterial rates of charged samples after c 20 min and d 180 min of bacteria incubation. All error bars = standard deviation (n = 3). P denotes DC+ charging and N denotes DC– charging. Significant differences between groups are marked with different letters (m–q, P < 0.05, SNK test in ANOVA)
