Protein-repellent and antibacterial polymeric composite. (A) Protein adsorption onto composites; (B) Dental plaque microcosm biofilm cfu of total microorganisms on composites cultured for 2 days. Note the log scale in y axis; (C–F) Representative live/dead images of biofilms on control composite, and composites with 3% MPC, 1.5% DMAHDM, and 3% MPC + 1.5% DMAHDM. The live bacteria were stained green, and the dead bacteria were stained red. Live and dead bacteria in close proximity yielded yellow/orange colors. In each plot, dissimilar letters indicate values that are significantly different from each other (p < 0.05). (Reproduced with permission from [43]. Elsevier, 2015)
