US Patent 10215672 Biocompatible method of functionalising substrates with inert surfaces

Biocompatible methods of functionalizing inert surfaces for use in biological applications are described. The methods employ the use of synthetic constructs of the generic structure F-S-L (where F is a functional moiety, S is a spacer selected to provide a construct that is dispersible in water, and L is a diacyl- or dialkyl-glycerophospholipid). An object of the invention is to localize or immobilize functional moieties to the inert surface of a substrate wherein the surface is comprised of glass, silver, polyamide, polycarbonate, polypropylene, polyethersulfone, polytetrafluoroethylene or polyvinylidene fluoride, and the substrate is comprised of a fiber, membrane, microsphere or nanosphere.
