Gold

The study of gold nanoparticles is very important in the field of nanomaterials because they have many potential applications. For example, they have been used the identification of the DNA sequences associated with disease, as well as bodily invaders like viruses. These nanoparticles could also serve as the basis for new technologies that will render obsolete the energy intensive methods currently used to fabricate computer semiconductors. These materials would therefore be excellent components of nanoelectronics, optics and biology.

Coalescence of Gold Nanoparticle
These videos present the phenomenon of coalescence which occurs in-situ in the HRTEM microscope. To produce it, the electron beam impinges into the sample. During the interaction the temperature rises and the Au particles come together.
