Abstract: The present invention provides compositions and methods for an improved coating for medical devices. Provided is a biofunctional coating composition comprising at least one binding domain that has binding specificity for a metallic surface material of a medical device, and at least one binding domain that has binding specificity for cells of endothelial cell lineage. Methods for coating a metallic surface of a medical device, and for manufacturing of a medical device, comprise contacting the metallic surface to be coated with the biofunctional coating material in an amount effective to form a coating, and may further comprise contacting the coated surface with cells of endothelial cell lineage to bind the cells of endothelial cell lineage to the coated surface.

Abstract: The presently disclosed subject matter relates to a peptide composition for non-covalently localizing fibrous connective tissue-inducing growth factor to a surface of an implant, the composition comprising a peptide having binding affinity for a surface material of an implant coupled to a peptide having binding affinity for a fibrous connective tissue-inducing growth factor. Methods are provided for delivering fibrous connective tissue-inducing growth factor GDF-7 in an amount effective to promote fibrous connective tissue repair and fibrous connective tissue formation. Also provided are methods of applying the peptide composition to an implant by contacting the composition with a surface of the implant; and kits comprising the compositions.

Abstract: Compositions are provided comprising a family of peptides having binding specificity for metal, and their use to produce coating compositions. The coating compositions are used to deliver a pharmaceutically active agent to metal, and are used in methods related to metal implants, metal repair, and metal-related diseases.
Abstract: A filter and method for removing selected materials from a biological fluid sample are provided. The filter comprises an outer housing, inlet, and outlet. A plurality of filter surfaces are provided within the outer housing, and at least one coating is applied to the filter surfaces. The at least one coating comprises at least two binding modules that are in turn selectively bound to one another. One binding module is selectively bound to the filter surfaces and another binding module is configured to bind selectively to the selected materials that are to be removed from the fluid sample. As the fluid sample is allowed to pass through the inlet, outer housing, and outlet, the selected materials are selectively bound to the filter surfaces via the coating, thus producing a filtered product at the outlet.

Abstract: The present invention provides compositions and methods for an improved coating for medical devices. The coating is an interfacial biomaterial (“IFBM”) which comprises at least one binding module that binds to the surface of a device (“surface-binding module”) and at least one binding module that performs another function (“affector module”) and which acts to inhibit biofilm formation.

Abstract: The present invention provides an improved coating for surfaces of medical implants. The coating comprises at least one interfacial biomaterial (IFBM) which is comprised of at least one binding module that binds to the surface of an implant or implant-related material (“implant module”) and at least one binding module that selectively binds to a target analyte or that is designed to have a desired effect (“analyte module”). The modules are connected by a linker. In some embodiments, the IFBM coating acts to promote the recognition and attachment of target analytes to surface of the device. The IFBM coating improves the performance of implanted medical devices, for example, by promoting osteointegration of the implant.
