Research output: Contribution to journalArticlepeer-review


The importance and implication of a newly developed Supramolecular NanoStamping (SuNS) technique with high information density is discussed. This technique enables the transfer of spatial together with chemical information from a master containing DNA features to a secondary substrate. Information transfer or copy of DNA, from a single stranded DNA (ssDNA) onto RNA, done by specific supramolecular interactions between pairs of complementary DNA, is the most frequent, efficient and dense information transfer in human life. SuNS comprises of three steps called hybridization, contact and dehybridization Dna wires of 30nm thick with 100nm pitch have been printed onto gold substrates through gold-thiol bonds. SuNS allows a printed pattern to be used as a master to print another copy onto a substrate of choice. SuNS transfers spatial information with chemical information. SuNS can be used for the production of multi component devices through the selective modification of ssDNA.
