Dual-functional nonfouling surfaces comprising target binding partner covalently coupled to polymer attached to substrate
First Claim
1. A block copolymer having a plurality of covalently coupled target binding partners having affinity toward a target molecule, the block copolymer having a first hydrophilic block and a second hydrophobic block, wherein the hydrophilic block comprises a plurality of carboxylic acid groups and a plurality of positive charged groups, wherein the hydrophilic block is substantially electronically neutral, and wherein the target binding partners are selected from the group consisting of enzymes, antibodies, protein-based antigens, receptors, polysaccharide ligands, and oligosaccharides ligands.

Abstract
Dual-functional nonfouling surfaces and materials, methods for making dual-functional nonfouling surfaces and materials, and devices that include dual-functional nonfouling surfaces and materials. The dual-functional surfaces are nonfouling surfaces that resist non-specific protein adsorption and cell adhesion. The dual-functional surfaces and materials include covalently coupled biomolecules (e.g., target binding partners) that impart specific biological activity thereto. The surfaces and materials are useful in medical diagnostics, biomaterials and bioprocessing, tissue engineering, and drug delivery.
