Abstract: Nanostructures made of noble metals (including Au, Ag, Pd, Pt, Rh, Ir and Ru) are finding widespread use ranging from biomedicine to energy production, electronics, and environmental protection. Controlled synthesis is one of the most effective strategies for precisely tailoring their physicochemical properties and thus optimizing their performance in certain applications. In the first part of this talk, I will introduce our recent studies on rational design and experimental synthesis of noble-metal nanocrystals with well-controlled shapes, sizes, and elemental compositions at the atomic level. In the second part, I will discuss our work on the applications of engineered metal nanostructures in clinical diagnostics. Examples of ultrasensitive and easy-to-use diagnostic techniques and their use in detecting cancer biomarkers from human blood samples will be highlighted.
