Terpolymer and polymer brushes for use against non-specific adsorption of substances from biological media

Abstract

A random terpolymer of N-(2-hydroxypropyl) methacrylamide, carboxybetaine methacrylamide and sulfobetaine methacrylamide, and a polymer brush and to a functionalized polymer brush containing this terpolymer are disclosed. The random terpolymer increases the resistance of the substrate surface to non-specific adsorption of substances from biological media and/or to non-specific interaction with biological media components, and is suitable for use in the form of a polymer brush, for example in sensors or membranes.
