Two clinical bacterial isolates were used to assess the antibacterial activity of copper within the different (n = 3). The higher the copper content, the lower the bacterial adherence (A). SEM imaging of S. aureus (BCI175) on pure PLGA layer (top row), on PLGA/aCaP layer (middle row), and on PLGA/CuTCP layer (bottom row) (B). Key: S. aureus = Staphylococcus aureus; S. epidermidis = Staphylococcus epidermidis; BCI = Bacterial Clinical Isolate. Statistical analysis by 1-way ANOVA revealed that for both strains all materials were significantly different from each other, except for the pair of PLGA/aCaP/CuO (1 %) and PLGA/CuTCP.
