Antibacterial and antibiofilm activities exerted by Cu coatings against the four bacterial pathogens E. coli, P. aeruginosa, S. aureus, and E. faecalis. The results are reported as the mean of the percentage of bacterial and biofilm inhibition ± standard deviation. Statistical analysis was performed compared to control experiments (100% of growth) using one-way ANOVA test. Differences were considered significant for p < 0.05 (* p < 0.05, ** p < 0.01, *** p < 0.001).
