Figure 3.

Fluorescent microscopy analysis of inhibition of biofilm establishment using peptide-coated surfaces. CLSM images of biofilms on uncoated and peptide-coated stainless steel surfaces developed at different incubation times. Viable bacterial cells are stained with SYTO 9 green fluorescent nucleic acid stain and dead bacterial cells are stained in red with propidium iodide (PI). On the left panel is biofilm formed by B. licheniformis and on the right, P. aeruginosa biofilm. The scale bar represents 50 μm.
