Representative live/dead staining images of biofilms adherent on PMMA discs cultured for 2 days: (a) control group, (b) 3% MPC group, (c) 1.5% DMAHDM group, and (d) 3% MPC+ 1.5% DMAHDM group. The live bacteria were stained green, and the dead bacteria were stained red. When live and dead bacteria were in close proximity or on the top of each other, the staining had yellow or orange colors. (Adapted from reference [75], with permission).
