Research Interests:

Ultrafast synthesis and 2D self-assembly of monolayer-protected gold nanoparticles

The Eah group has been working on development of a new ultrafast synthesis method for colloidal gold nanoparticles and their 2D self-assembly into a monolayer film using a toluene droplet. In addition to basic science study of gold nanoparticles, several application projects are under way including surface-enhanced Raman scattering, nanoparticles memory, nano-drum, and catalysis by gold.
