Although gold is not a biomaterial per se, its nanomaterials have found widespread use in a variety of biomedical applications owning to their unique properties, including bio-inertness, tunable photoluminescence, radioactivity (for 198Au and 199Au), and strong scattering and absorption of light in the near-infrared region. Over the past decade, numerous methods have been developed for producing gold nanomaterials in the quality, quantity, and reproducibility required for a systematic study of their properties as a function of size, shape, and structure, as well as for the full exploration of their applications in biological studies and nanomedicine. In this talk, I will briefly discuss some of the new developments, with a focus on the rational design and controlled synthesis of gold nanomaterials for optical bioimaging, drug delivery, and cancer theranostics.

Disruptive technologies enabled by nanoscale materials and devices will define our future in the same way that microtechnology has done over the past several decades. Our current research centers on the design and synthesis of novel nanomaterials for a broad range of applications, including nanomedicine, regenerative medicine, cancer theranostics, tissue engineering, controlled release, catalysis, and fuel cell technology.
