Abstract
Abstract A membrane mimetic structure having a hydrophilic outer portion and a hydrophobic inner portion is covalently bound to a surface having reactive functional groups. The membrane mimetic structure consists essentially of adjacent amphiphilic molecules independently covalently bound to the surface. The structures can be applied to surfaces and should find application in a wide variety of disciplines requiring surfaces exhibiting properties of biological membranes.

Claim 1
Independent Claim
122 words
A method for forming a membrane mimetic structure on a surface having covalently bound nucleophilic functional groups, said structure having a hydrophilic outer portion and a hydrophobic inner portion and consisting essentially of a monomolecular layer of adjacent amphiphilic molecules independently covalently bound to said surface through at least a portion of the nucleophilic functional groups, said method comprising the step of contacting said surface with a cyclic dicarboxylic anhydride of the formula ##STR6## wherein n is an integer from 8 to 14, said step being conducted under conditions conducive to the reaction of the nucleophilic group and said cyclic anhydride, said reaction being conducted until the covalently bound amphiphilic molecules sterically hinder further reaction with the nucleophilic groups on the surface.
