Schematics of anti-dot arrays fabrication. Starting material is AAO templates coated with a thin conductive layer. (1) Secondary mold injection. Metal secondary mold can be electrochemically deposited into channels while polymer mold spontaneously covers the channels. (2) Free standing secondary mold is obtained by selective etching of AAO template. (3) Polymer/metal antidot arrays are formed by wetting or electrochemical deposition, respectively.
