Bacterial biofilm concentration per area unit (CFU/cm²) (A) and planktonic bacterial concentration (ABS) (B) of S. aureusATCC 29213, S. epidermidis ATCC 35984, E. coli ATCC 25922, and P. aeruginosa ATCC 27853 on coatings: ControlA, hc.LNZ, hc.LEV, and LNZ-LEV. Error bars represent the interquartile range. *p < 0.05, **p < 0.01, ***p < 0.001 (Wilcoxon test). Backscattered electron SEM micrographs of coating surfaces after 24 h of bacterial incubation: (left) ControlA and (right) LNZ-LEV, showing the biofilm in S. aureus, S. epidermidis, E. coli and P. aeruginosa in panels (C, D), (E, F), (G, H), and (I, J), respectively.
