Background: Porphyromonas gingivalis adherence to Streptococcus gordonii may be important for P. gingivalis colonization in the oral cavity. Nanoparticles encapsulating synthetic peptide BAR (BAR-NPs) inhibit P. gingivalis adherence more potently than free BAR. However, BAR-NPs would exhibit low retention in an open flow environment. Hypothesis: Targeting BAR-NPs to the streptococcal surface using CafA protein will enhance their efficacy. Methods: CafA-modified NPs encapsulating BAR were synthesized using double emulsion approach. Surface binding and retention, and release kinetics of BAR from CafA-modified NPs was assessed. Functional inhibition assays were performed using dual a species biofilm. Results: CafA-modified NPs demonstrated specificity of adhesion, …
