Figure 4From: Chitosan against cutaneous pathogens Fluorescence confocal microscopy shows chitosan-bacteria interaction. CTC-stained P. acnes bacteria were (A) left untreated or (B, C) incubated for one hour with FITC-labeled chitosan, and then examined by fluorescence microscopy. Scale bar is 2 μm (A, C) or 10 μm (B). Bacteria is red, while chitosan is green.Back to article page
