Polymer cushion lipid bilayer
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.
