Paint with water: A topographically patterned agarose hydrogel stamp transfers and prints water onto uniformly charged PMMA electrets for selectively discharging electrostatic charges. The high-resolution electrostatic charge patterns produced by this simple approach can induce the reduction of metal ions and allow the fabrication of micro- and nanoscale metallic arrays.
