Transfer-printing of highly aligned DNA nanowires

J Am Chem Soc. 2003 Jun 18;125(24):7162-3. doi: 10.1021/ja034185w.

Abstract

We developed a simple method of reproducibly creating highly aligned DNA nanowires without any surface modifications or special equipment. Stretched DNA molecules initially present on the PDMS sheet were transferred onto another surface using transfer-printing (TP). Fluorescent microscopic and atomic force microscopic images revealed that many DNA molecules were highly aligned on surfaces after TP. Furthermore, it was also possible to realize the two-dimensional assembly of DNA nanowires by repeating TP.
