Gold Nanoparticles

Caption: Left: This is a transmission electron microscopy (TEM) image of a single CVB3 virus showing tens of gold nanoparticles attached to its surface. The particles form a distinct "tagging pattern" that reflects the shape and the structure of the virus. The TEM image can be correlated to the model of the virus (right), where the yellow spheres mark the possible binding sites of the gold particles. The diameter of the virus is about 35 nanometers (nanometer = one billionth of a millimeter).
