Fig. 7From: BAR-encapsulated nanoparticles for the inhibition and disruption of Porphyromonas gingivalis–Streptococcus gordonii biofilmsDisruption of established P. gingivalis/S. gordonii biofilms after different exposure times to BAR surface-modified NPs, BAR-encapsulated NPs and free BAR. Biofilms were visualized with confocal microscopy and the ratio of green (P. gingivalis) to red (S. gordonii) fluorescence in z-stack images was determined using Volocity software.
