From: An antibacterial coated polymer prevents biofilm formation and implant-associated infection

Optical and SEM images of PEEK plates removed from the infection mouse model. On Day 14, implanted PEEK plates were removed from the SGM and washed 3 times in phosphate buffered saline (PBS). The bacterial bioluminescent signals were then captured by BLI. A strong signal was observed on the surface of the non-coated PEEK, but not on the PEEK-Ag+ (A). The signal on the non-coated PEEK was significantly greater than that on the PEEK-Ag+ (p = 0.0005) (B). The microstructures of the surface of these PEEKs were analyzed by SEM. S. aureus (arrows; C) and its biofilm (arrowheads; C) were seen on the surface of the non-coated PEEK, but not on the PEEK-Ag+ (D). Results shown are means ± standard errors of the mean (SEM).
