A thin film of crosslinked poly(acrylic acid) (PAA) , patterned within microfluidic channels (see figure) and crosslinked with metal cations, serves as a platform for rapid “on‐chip” growth of patterned metallic and semiconductor nanoparticles. The embedded particles serve as catalysts for electroless deposition of metal films.
