Fig. 3From: BAR-encapsulated nanoparticles for the inhibition and disruption of Porphyromonas gingivalis–Streptococcus gordonii biofilmsBAR-encapsulated PLGA NPs prevent P. gingivalis adherence to S. gordonii. 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 image analysis software.
