A positively charged polyvinyl N ‐methylpyridine (PVMP) polymer is patterned on a solid substrate via photochemical crosslinking, with the resultant cationic surface directing the adsorption of water‐soluble Au nanoparticles, producing patterned nanostructured conductive films (see figure). These surfaces could be further modified with thiol ligands allowing fine‐tuning of surface wettability and biocompatibility.
