Colloidal Metal Nanocrystals: Controlled Synthesis and Applications in Medical Diagnostics

Nanocrystals made of noble metals (including Au, Ag, Pd, Pt, Rh, Ir and Ru) are finding widespread use ranging from biomedicine to energy conversion, 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. Although the first documented synthesis of metal nanocrystals can be traced back to the fantastic work on Au colloids by Michael Faraday in the 19th century, only within the past few decades have the methodologies become available for generating nanocrystals with well-controlled structures (i.e., shapes, sizes, and chemical compositions). In the first part of this talk, I will introduce my recent studies on rational design and experimental synthesis of noble-metal nanocrystals with desired structures at the atomic level. In the second part, I will discuss my 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.
