Post-charging antibacterial mechanism analysis. a, b Total discharging capacity of TNT-C-15 in a 0–20 min and b 6–20 min after AC/DC+ charging for 0.5, 5, and 15 min (*denotes P < 0.05, Student t test). c Potential curves of DC+ charged TNT-C-15, DC+ charged TNT, AC charged TNT-C-15, AC charged TNT, DC– charged TNT-C-15 and DC– charged TNT with solid/dashed lines denoting with/without bacteria, respectively. The pre-charging time is 15 min. d ORP in the LB medium during and after the charging process (**denotes P < 0.01 compared with the control group, Student t test). All error bars = s.d. (n = 3)
