Welcome to Xie group

GOLD (and SILVERforms the heart of our research life. Throughout the few thousand years of recorded human history, these precious metals have immense economic value. Besides its monetary value, science has exploited the nanosized versions of these precious metals for numerous applications. Gold (and silver) at size scale in the nano and sub-nano range, begins to have many intriguing physical and chemical properties. These exciting functionalities open up a whole new universe of possible chemistry and applications. These applications will significantly increase the values of Au and Ag as functional materials other than its current main role of wealth storage. It is this new universe that has captivated our passion to design gold- and silver-based functional materials to address challenging issues in healthcare and the environment, throughout our entire scientific journey. Our research at NUS is highly interdisciplinary and lies at the intersection of engineered metal nanoparticles/nanoclusters and the biological world. In the past ten years, we strategically blended all our research experience in the fields of chemistry, materials science, chemical engineering, biology, and medicine into our own niche area at NUS, that is, Engineering ultrasmall gold (and silver) nanoclusters for biomedical and catalytic applications.
