abstract

  • Copyright © 2017 American Scientific Publishers All rights reserved. Tobacco mosaic virus (TMV) is used as an organic biotemplate to prepare hybrid materials with silver nanoparticles (AgNPs). In this study, the native rod-like TMV structure was transformed into spherical particles using a thermal treatment; subsequently, the external surface of the thermally-treated TMV (TT-TMV) were in-situ covered with AgNPs through cycles of sequential reduction using sodium borohydride. The as-grown nanoparticles show a bimodal distribution on the surface of the TT-TMVs after the fifth nucleation cycle. Results of characterization of the metallized TT-TMV by dynamic light scattering, transmission electron microscopy, atomic force microscopy, and energy-dispersive X-ray spectroscopy accordingly show the effect of cycling on the morphology of the AgNPs/TT-TMV hybrids.
