Antimicrobial efficacy of PVP foils and nanofiber mats with different ciprofloxacin payloads applied on wounds infected with planktonic bacteria in a biofilm. (a) Representative pictures of untreated and treated wounds after 40 h of incubation. (b,c) Bacteria count in tissue extracts of wounds treated with foils (b) or nanofiber mats (c). (d) Bacteria counts in control wounds treated with plain PVP foils prepared from solutions in water or 30% acetic acid. Means and standard deviations of three independent experiments (three donors) run in triplicate are reported. Cipro—ciprofloxacin; AcCOOH—acetic acid.
