| Exploring the Many Uses of Metallic Nanocrystals | |
|
Professor Wang Jianfang of Department of Physics has been working extensively on plasmonic metal nanoparticles, in particular the colloidal plasmonic metal nanocrystals. The valuable contributions that he and his team have made to the growth, properties, and applications of the materials also advance the research of nanoplasmonics. Plasmon resonance absorbs and reflects light depending on the size of nanoparticles, and exhibits wavelengths which span across the ultraviolent-infrared spectrum. When the wavelengths fall under the visible light spectrum, different colours will present. The colour-changing nature of nanocrystals make them widely be adopted in food and medicine safety monitoring, as well as pregnancy and genetic tests.
His research work most recently has seen him awarded the Croucher Senior Research Fellowship 2020 and given rise to two spinoff companies focusing on the supply of nanoparticles to researchers and manufactures worldwide.
