Self-Assembly of Metal–Virus Nanodumbbells (original) (raw)

The study presents a method for the selective attachment of gold nanoparticles to the ends of tobacco mosaic virus (TMV) using RNA as a mediator. By mixing a gold sol with TMV, researchers achieved a high degree of labeling, resulting in unique gold-virus-gold nanodumbbell structures. Characterization through transmission electron microscopy (TEM) and atomic force microscopy (AFM) demonstrated the successful binding of gold nanoparticles, which offers a promising template for the development of novel nanomaterials.
