Evaluation of anti-adhesive properties of films based on gold (Au), Chitosan (Ch_Buffer), and chitosan–N-acetylcysteine (Ch_NAC4). (A) S. aureus adhesion on Au, Ch_Buffer, and Ch_NAC4 films after 2 h incubation in growth medium (white bars) and 4 h re-incubation on fresh growth medium after the 2 h pre-incubation period (black bars). (B) S. aureus adhesion on Au, Ch_Buffer, and Ch_NAC4 after 2 h incubation in phosphate-buffered saline (PBS) or PBS supplemented with 1% human plasma. (C) Mass of proteins from 1% (v/v) human plasma adsorbed on Au, Ch_Buffer, and Ch_NAC4 surfaces. (D) Effect of Au, chitosan, and thiolated chitosan on S. aureus total biofilm biomass formation.
