The industry has shrunk the central elements of their computer chips to fourteen nanometers in the last sixty years. Conventional methods, however, are hitting physical boundaries. Researchers around the world are looking for alternatives. One method could be the self-organization of complex components from molecules and atoms. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and Paderborn University have now made an important advance: the physicists conducted a current through gold-plated nanowires, which independently assembled themselves from single DNA strands. Their results have been published in the scientific journal <i>Langmuir<\/i>.<\/p>\n<p>At first glance, it resembles wormy lines in front of a black background. But what the electron microscope shows up close is that the nanometer-sized structures connect two electrical contacts. Dr. Artur Erbe from the Institute of Ion Beam Physics and Materials Research is pleased about what he sees. \u201cOur measurements have shown that an electrical current is conducted through these tiny wires.\u201d This is not necessarily self-evident, the physicist stresses. We are, after all, dealing with components made of modified DNA. In order to produce the <a href=\"http:\/\/phys.org\/tags\/nanowires\/\" rel=\"tag\" class=\"\">nanowires<\/a>, the researchers combined a long single strand of genetic material with shorter DNA segments through the base pairs to form a stable double strand. Using this method, the structures independently take on the desired form.<\/p>\n<p>\u201cWith the help of this approach, which resembles the Japanese paper folding technique origami and is therefore referred to as DNA-origami, we can create tiny patterns,\u201d explains the HZDR researcher. \u201cExtremely small circuits made of molecules and atoms are also conceivable here.\u201d This strategy, which scientists call the \u201cbottom-up\u201d method, aims to turn conventional production of electronic components on its head. \u201cThe industry has thus far been using what is known as the \u2018top-down\u2019 method. Large portions are cut away from the base material until the desired structure is achieved. Soon this will no longer be possible due to continual miniaturization.\u201d The new approach is instead oriented on nature: molecules that develop complex structures through self-assembling processes.<\/p>\n<p><!-- Link: <a href=\"http:\/\/m.phys.org\/news\/2016-11-genetic-material-electricity-dna-based-nanowires.html\">http:\/\/m.phys.org\/news\/2016&#45;11-genetic-material-electric...wires.html<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tinier than the AIDS virus\u2014that is currently the circumference of the smallest transistors.
