Diffusion of Macromolecules in Model Oral Biofilms▿

By Shoji Takenaka, Betsey Pitts, Harsh M. Trivedi and Philip S. Stewart

Abstract

The diffusive penetration of fluorescently tagged macromolecular solutes into model oral biofilms was visualized by time-lapse microscopy. All of the solutes tested, including dextrans, proteases, green fluorescent protein, and immunoglobulin G, accessed the interior of cell clusters 100 to 200 μm in diameter within 3 min or less
