Fabrication of micro-nano hybrid patterns on a solid surface.
A hybrid pattern with micropatterned nanoarray of Au-Pt core-shell particles in the background of Au nanoarray was fabricated via an approach combining photolithography, block copolymer micelle nanolithography, and controlled seed growth. Two pertinent patterns were also obtained: one is a hexagonal nanopattern of Au-Pt bimetallic nanodots with controlled thickness of Pt shells, and the other is an interlaced pattern of Pt microsheets and Au nanoarrays. We thus present a platform to generate regular micro-nano patterns of one or more than one metal on a solid surface.
