filter terms:

Site-selective biomineralization of Au nanostructures in the interior channel of Tobacco Mosaic Virus (TMV) is achieved by mutating threonine 103 in TMV to cysteine (T103C-TMV) to introduce the strong coordination interaction between the arrayed sulfhydryl ligands and gold species. By finely tuning the reaction conditions, Au nanoparticle chains and Au nanorods are successfully and exclusively synthesized inside the T103C-TMV nanotubes. © 2015 WILEY-VCH Verlag GmbH & Co.
