Biofilms are mostly water and small solutes can move by diffusion in the watery matrix of the biofilm.

 
Inside biofilm cell clusters, solutes move by a combination of fluid flow (convection) and diffusion.
Extracellular polymeric substances (EPS) can prevent stains, antibiotics, or nutrients from reaching the inside of biofilm cell clusters.
Diffusion is the predominant solute transport process within cell aggregates.
