Interests

ㅤOur research interests are focused on the chemistry of nanoscale materials, especially on the rational design and control of the nanoparticles in the fluids (i.e.ㅤsolution, gases and biosystem). We have demonstrated their unique physical, chemical and optical properties, which includes understanding the characterization of both single and bulk-assembly of the nanoparticle. We are now building the brand-new concept of nanoplatform for analysis of target chemicals and biomolecules, which will be exploited for lots of potentials for broad applications (such as catalysis, sensors and diagnosis).
