摘要
The present invention provides a method for producing biomolecular coatings on devices having gold surfaces. The method describes the production of recombinant fusion proteins consisting of one or more polypeptide domains of interest and a high affinity gold binding peptide consisting of 1 to 7 repeats of a gold binding protein (GBP) sequence. By this method, many biologically active polypeptides lacking intrinsic gold-binding properties can be firmly attached to gold surfaces. By exploiting such gold binding properties, devices are disclosed which comprise such coatings that are useful as prosthetic devices, implants, and tissue interfacing materials. Further, such devices comprising these coatings protect surfaces from fouling and impart various properties to the coated devices.
