报告摘要：

The recent nanoscience revolution has witnessed the rapid development of a variety of remarkable

nanoscale materials. However, one major technological challenge is to fabricate useful bulk materials

and devices from functional nano-scale building blocks. In this talk, I will first show several

examples on how to use the principles of soft condensed matter physics, especially colloidal physics,

to guide the solution-processing of nanomaterials and the construction of useful structures from

nanoparticles. The studied nanomaterials, catalogued by their dimensions, include 0-dimension (0D)

quantum dots, 1D carbon nanotubes, and 2D inorganic nanoplatelets. Then, I will introduce a novel

system that utilizes the biomolecular recognition, especially the hybridization of complementary

single-stranded DNA, to organize nanoparticles into well-defined clusters and 3D superlattices. This

unique system allows for the systematic investigation on the collective properties of nanoparticles in

these assemblies with precisely controlled positions and inter-particle distance.
