WebApplication of the lipid bilayer on the sensor’s surface can be achieved via direct adsorption, usually owing to self-assembling monolayers (SAM) or deposition on a polymer cushion [107]. Tethering [102] ( e.g. by silanelipids and thiolipids) and application of a polymer substrate ( e.g . agarose) are preferred for the transmembrane proteins. WebA novel continuum model is proposed to describe the deformations of a planar lipid bilayer suspended across a circular pore. The model is derived within a new theoretical framework for smectic A liquid crystals in which the usual director n, which defines the average orientation of the molecules, is not constrained to be normal to the layers.
