Abstract
Gold nanoparticles are included in the group of metallic nanoparticles, and their application has become possible recently because of new optical equipment, electronic devices, and probes capable of manufacturing, detecting, and identifying biomolecules of medical interest. Among the range of nanoparticles, one stands out: the gold nanoparticle. It doesn't possess toxic characteristics and can be administered in vivo. In this study, the structural, optical and electronic properties of gold nitrate were investigated using the density functional theory formalism, considering the gradient generalized approximation. Finally, we observe its application in nanobiotechnology, specifically photothermal applications.
