Diffusion of macromolecules in model oral biofilms.

Shoji Takenaka¹, Betsey Pitts, Harsh M Trivedi, 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 microm in diameter within 3 min or less.
