Liquid supramolecular nanostamping (LiSuNS) is an efficient stamping technique that replicates various DNA features with no need of solid surface contact. LiSuNS is based on the specific interaction of complementary DNA strands. An original pattern composed of multiple DNA strands on a rough surface can be copied onto a liquid prepolymer that is subsequently hardened, leading to a solid surface that displays the mirror image of the master used.
