In recent years, nanomedicine focused on the development of functional AuNPs for biomedical imaging, attributed to the intriguing optical properties of these nanoparticles, which are discussed in this review. Moreover, are presented the most important in vivo diagnostic techniques which have benefited from the development of engineered AuNPs, such as computed tomography and photothermal/photoacoustic imaging. Another important advantage related to these nanoparticles refers to their excellent performance in recent in vivo studies and clinical trials. Also, side effects of conventional drugs have been minimized by conjugation of AuNPs.
