Peptide-induced patterning of gold nanoparticle thin films

► Patterned catalytic peptides using soft lithography lift-off and deposited patterned gold nanoparticles. ► Demonstration patterned deposition of conducting gold nanoparticles using low concentration aqueous solution ► Demonstration of patterned deposition of conducting gold nanoparticle layers using higher concentration of aqueous solution. ► Compared covalently attached proteins with physically adsorbed proteins and peptides for patterned deposition.
