Intra-colony channel morphology in Escherichia coli biofilms is governed by nutrient availability and substrate stiffness

This study shows that nutrient availability and substrate stiffness influence intra-colony channel morphology in E. coli biofilms, with glucose-limited biofilms having wider central channels.

Functional channels in mature E. coli colonies

The paper studies E. coli biofilms using Mesolens to identify functional channels that transport particles and aid nutrient absorption, suggesting new strategies for drug delivery.
