[Webinar] Physical mechanisms of the interaction between lipid-based membranes in aqueous environments

In the congested environment of cells and tissues, the interaction between the surfaces of biomolecular assemblies — notably biomembranes — is of paramount importance for numerous biological processes. This lecture reviews various mechanisms underlying the interaction between lipid-based membranes in their aqueous (physiological) surroundings. The lecture covers van der Waals interactions, electric double-layer forces, solvent- and solute-mediated forces, as well as undulation-induced forces and forces associated with the conformation of membrane-associated polymers. Experimental aspects as well as continuum-theoretical descriptions and atomistic computer simulations are discussed.
