Abstract

The present invention relates to a method for preparing a nanowire crossbar structure, comprising: (a) providing a substrate; (b) depositing thereon a composite structure comprising a nucleic acid-block copolymer having equidistant nucleic acid-catalyst binding sites and at least one catalyst nanoparticle functionalized to bind specifically to nucleic acid segments of the copolymer; (c) applying a directed gas flow and/or an alternating electric field onto the composite structure; and (d) applying chemical vapor deposition techniques, a use of such a structure and a structure obtainable by such a method.
