Contact printing beyond surface roughness: Liquid supramolecular nanostamping

Research output: Contribution to journalArticlepeer-review


A new technique, Liquid supramolecular nanostamping (LiSuNS), has been proposed that eliminates the need for contact between two solid surfaces and enables true large-scale high-efficiency replication of DNA-based features. LiSuNS successfully shares SuNS's main advantages including the ability of printing features made of different DNA sequences in a single printing cycle, while preserving their chemical differences. When a master contains 3D features coated with single-stranded DNA, LiSuNS reproduces both the 3D spatial information and its chemical composition (1D) independently, suggesting the 4D printing approach. 4D printing could also be used to efficiently stamp DNA features directly onto objects such as needles or microfluidics elements, thus substantially increasing their potential applications.
