摘要:
A method is provided for immobilizing a bioactive molecule onto a surface using polyphenol oxidase. In the presence of polyphenol oxidase, a bioactive molecule containing a phenol or catechol group can be simply in situ oxidized within a short time to dopa or dopaquinone which forms a coordinate bond with a metal or polymer substrate, thus immobilizing the bioactive molecule onto the surface with stability. Based on the surface immobilization of bioactive molecules using polyphenol oxidase, various bioactive molecules such as osteogenetic peptides and growth factors can be simply immobilized to medical metal or polymer substrate surfaces such as orthopedic or dental implants which can be then effectively used to induce rapid osteogenesis after being transplanted. Also, antithrombotic agents and/or entothelialization inducing agents may be immobilized to medical substrates for vascular systems, such as stents and artificial blood vessels, thus guaranteeing hemocompatibility to the medical substrates.
