Invited by Key Laboratory of Photochemical Conversion and Optoelectronic Materials, Technical Institute of Physics and Chemistry (TIPC), Chinese Academy of Sciences, Prof. Jianping Xie from National University of Singapore visited TIPC on July. 14 and gave an academic report entitled Engineering Ultrasmall Metal Nanoclusters for Biomedical and Environmental Applications. 

In very recent years, ultrasmall metal nanoclusters with core sizes below 2 nm have emerged as a new class of functional nanoparticles due to their discrete and size dependent electronic structures and molecular-like properties, such as HOMO-LUMO transitions in optical absorptions, quantized charging, and strong luminescence. Synthesis of high quality metal nanoclusters in sufficiently large quantities is necessary for establishing reliable size-property relationships and exploring potential applications.
