Abstract

Abstract : A facile method for in situ fabrication of three-dimensional gold nanoparticles micropatterns throughout a polyethylene glycol hydrogel substrate has been developed by combining photochemical synthesis of gold nanoparticles with photolithography technology. Abstract : A facile method for in situ fabrication of three-dimensional gold nanoparticle micropatterns in a cell-resistant polyethylene glycol hydrogel has been developed by combining photochemical synthesis of gold nanoparticles with photolithography technology. The gold nanoparticle micropatterns were further bio-modified with cell integrated polypeptide NcysBRGD based on a gold–thiol bond to improve cell behaviors. Primary cell tests showed that NcysBRGD can enhance cell adhesion very well on the surface of gold nanoparticle micropatterns.
