Just-Accepted Paper: Thiol-mediated DNA-templated silver nanofibers
23 April 2012. Our manuscript "Thiol-Mediated Anchoring of Silver Cations to DNA for Construction of Nanofibers on DNA Scaffold", which describes the results of a collaborative work led by A. Zinchenko (Nagoya University), has just been accepted for publication in Biomacromolecules.

Abstract: Formation of metal-containing Ag-mercaptoethanol (-Ag-S(R)-)n complexes on DNA chain scaffold was studied by UV spectroscopy, zeta potential method, fluorescence and transmission electron microscopies. Experimental results made clear the mechanism of DNA mineralization and compaction according to which intercalation of silver cations into DNA scaffold and further formation of (-Ag-S(R)-)n oligomeric complexes on DNA induces efficient DNA chain compaction by terminal Ag+ cations. By transmission electron microscopy the formation of fiber-like DNA-templated nanostructures was observed. DNA-Ag-thiol complexes are promising for DNA-templated engineering of hybrid onedimensional nanostructures with adjustable chemical functionalities by choosing appropriate thiol ligand.
