Bacterial adhesion to PLGA and PLGA/Ag nanocomposite films. S. aureus and E. coli cell adhesion to PLGA and PLGA/Ag was determined as colony forming units (CFU/mL) after 3 h incubation at 37 °C. Data are expressed as percentage of the ratios between CFU of bacteria adherent to PLGA to CFU of bacteria adherent to 24-well flat-bottom sterile polystyrene microplates. The values represented are the means of the results of each sample performed in duplicate and repeated in three separated experiments. Error bars indicate standard errors of the means. The statistical significance was indicated as follows: * p < 0.05 and ** p < 0.01.
