Biophysical properties of material-colonizing fungal biofilms: multiscale structural and mechanical characterization

This paper develops a multiscale methodological workflow to characterize the structural and mechanical properties of fungal biofilms formed by Knufia petricola, revealing how nitrogen source affects biofilm morphology and stiffness.

E. coli extracellular matrix: a tunable composite with hierarchical structure

This study investigates how the composition and interaction of curli fibers and pEtN-cellulose in E. coli biofilms influence their mechanical properties and structure.

Charged agar surfaces affect E. coli biofilm properties by balancing curli amyloid quantity and quality

This study shows that charged agar surfaces alter E. coli biofilm properties by influencing curli amyloid quantity and quality, affecting structure and stability.

Osmotic pressure gradients in E. coli biofilms revealed by in-situ sensors

The paper develops liposomal nano-sensors to measure osmotic pressure gradients in E. coli biofilms, revealing radial increases linked to biofilm structure, metabolism, and expansion.

Cortical Tension Links Curvature to Tissue Growth in the Cellular Potts Model

The paper uses the Cellular Potts Model to show that tension-dependent local proliferation drives curvature-driven tissue growth via surface tension, without soluble growth factors.

Mechanical comparison of Escherichia coli biofilms with altered matrix composition: a study combining shear-rheology and microindentation

This study compares the mechanical properties of E. coli biofilms with altered matrix composition using shear-rheology and microindentation, showing the role of curli fibers and pEtN-cellulose in stiffness and structure.
