(A) Schematic of experimental setup for treatment of in vitro biofilm with HOCl that is produced and the e-scaffold reaction. The e-scaffold was placed on top of a biofilm grown in one of the 6-well plates. Chloride ions supplied by the 0.9% PBS are oxidized to chlorine at the working electrode when a positive potential is applied to the working electrode. Chlorine dissociates into the solution to form HOCl driven by the pH of the solution. (B) Experimental setup used to measure pH profiles. For HOCl profiles, a Gamry© Interface 1000ETM was used instead of the electrometer/ammeter and ADC. The figures are not drawn to scale.
