Adhesion in Biological Systems

Adhesion in biological systems.

The primary structure ol proteins results from the combination of amino acids in a proper sequence through peptide bonds which tire covalent bonds. Stabilization of ano-helical configuration by hydro­ gen bonding yields a secondary structure. I he spiral is stabilized by hydrogen bonding between the car­ boxyl and the imido groups of the peptide chain which appear in a regular sequence along th...

Cooperativity in biological systems

Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...

On the mechanism of adhesion in biological systems

I study adhesion relevant to biological systems, e.g., flies, crickets and lizards, where the adhesive microstructures consist of arrays of thin fibers. The effective elastic modulus of the fiber arrays can be very small which is of fundamental importance for adhesion on smooth and rough substrates. I study how the adhesion depend on the substrate roughness amplitude and apply the theoretical r...
