For explorative work in methodology. The surface consists of dextran modified with lipohilic compounds. The capturing process permits the liposome to retain the lipid bilayer structure, meaning that injected liposomes may carry membraneanchored molecules that protrude on one or both sides of the lipid bilayer. High capacity for increased sensitivity. The surface can be regenerated to its original appearance after liposome binding and interaction analysis, allowing repeated meaningful analysis.
