Fig. 5.

Confocal microscopy images of S. aureus after staining with LIVE/DEAD® BacLight™ Bacterial Viability Kit incubated on CTL and HTE at five representative time points over 21 days. Live cells stain fluorescent green, whereas bacteria with damaged membranes stain fluorescent red. The top panels represent as-received CTL, and the bottom panels represent the matching time point HTE samples incubated with S. aureus (n ​= ​3). Scale bar ​= ​20 ​μm.
