Novel nanopatterning technique uses liquid bridge to transfer materials from mould to substrate
Many nanotechnology research projects require some form of nanopatterning technique in fabricating the devices, structures and surfaces required. With the current state of micro- and nanofabrication, the direct printing of functional materials is the most efficient method at low cost and low environmental impact. A direct printing approach has the merits of forgoing complex and expensive equipment, reducing the fabrication processes, saving the amount of material used, and removing chemical exposure in the processes. However, imprinting methods suffer from residues and difficulty in multi-alignment. Researchers in Korea have now developed a direct printing technique that is based on a liquid-bridge-mediated transfer moulding process...
