Production of Platinum Atom Nanoclusters at One End of Helical Plant Viruses

Figure 6

Nanoparticles of platinum fill the inner canal of the TMV VLP. TEM images of Pt nanoparticles in the inner canal of the virus-like rods produced from the coat protein of TMV. Incubation of VLP with (dien)platinum followed by electroless deposition of Pt atoms took place under the same conditions as with TMV. Inset in the upper corner indicates clearly the coat protein tube around the Pt nanoparticles. No contrasting of specimen was done.
