Effects of surfactants on drug delivery and antimicrobial activity. (a) Schematic representation of the protocol used to test the antimicrobial efficiency of the tested formulations. (b) Antimicrobial activity of ciprofloxacin (applied doses: 10 µg/wound) in different formulations in terms of CFU reduction with respect to untreated infected wounds (n = 4). Significance values with respect to untreated controls: *** p < 0.001; ** p < 0.01; * p < 0.05; # p > 0.05.
