Nanotransfer printing (nTP) technology offers outstanding simplicity and throughput in the fabrication of transistors, metamaterials, epidermal sensors, and other emerging devices. Nevertheless, the development of a large-area sub-50 nm nTP process has been hindered by fundamental reliability issues in the replication of high-resolution templates and in the release of generated nanostructures. Our group presented a solvent-assisted nanotransfer printing (S-nTP) technique based on high-fidelity replication of ultrahigh-resolution (8 – 20 nm scale) patterns using a dual-functional bilayer polymer thin film. For uniform and fast release of nanostructures on diverse receiver surfaces, interface-specific adhesion control was realized by employing a polydimethylsiloxane (PDMS) gel pad as a solvent-emitting transfer medium, providing unusual printing capability even on biological surfaces such as human skin and fruit peels.
