Scientists have developed a method of ‘twisting’ segments of DNA to create Mobius bands, closed structures with only one side. A complex version of the structure can be used in the future for molecular engineering, the Nature Nanotechnology magazine said.
A Mobius strip can be made by twisting a strip of paper 180 degrees and taping the ends together. Similar structures are found in nature, but until now, scientists were unable to create them artificially on a molecular level.
The authors of the study, Chemists from Arizona State University in the United States, call the technique of recreating DNA fragments with paper, DNA 'kirigami'.
