Both systems consist of a lipid bilayer, which is de-coupled from an underlying support by a spacer cushion. Both systems will be reviewed, with an emphasis on the effect that the spacer moiety has ... 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.
