报告简介：

The structure-dependent optical, electrical, magnetic, and catalytic properties of metal, semiconductor, and metal oxide nanoparticles have stimulated intense research and developments in chemistry, materials sciences, biology and medicine. The ability to control structural integration of functional materials at nanometer scale opens the access to heterogeneous nanohybrids with functionalities that are not available in individual building blocks. Emerging properties of the heterogeneous nanohybrids hold great promise in catalysis, theranostics, and combination therapy, in which the synergistic action of multiple components is necessitated for optimal performance. On the other hand, there is growing fundamental and practical interest in developing ordered ensembles of metal, semiconductor, and magnetic nanostructures, in which tailored interactions of surface plasmons, excitons, or magnetic moments of the nanostructures give rise to emerging collective properties distinctively different from those of individual building blocks. This talk summarizes our recent work in developing heterogeneous nanostructures and well-defined assemblies that were not easily accessible by traditional colloidal chemistry. We have shown that our strategies based on the use of reactive polymers offers new opportunities in addressing some fundamental challenges in surface enhanced spectroscopy, microfluidics, and catalysis.
