摘要
(Figure Presented) All wired up: Robust 1D scaffolds have been designed based on the i tetraplex by a strategy of inducing bidirectional growth on "slipped" tetraplexes. The growth propagates through non-Watson-Crick base-pairing and leads to nanowires more than 3 μm long. These nanowires have been characterized by microscopy (AFM and TEM, see picture), surface-enhanced Raman spectroscopy, and circular dichroism spectroscopy. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
