Antibacterial effects in different charging modes. a Antibacterial effect on E. coli and S. aureus triggered by AC. b On-charging antibacterial effects of TNT-C-15 on E. coli during the charging process. c Post-charging antibacterial effects of TNT-C-15 on E. coli after charging for different time. d Overall antibacterial curves of TNT-C-15 on E. coli triggered by AC, DC+ and DC–. All error bars = s.d. (n = 3). Significant differences between groups are marked by different letters (m–o, P < 0.05, SNK test in ANOVA)
