Colloidal semiconductor nanoparticles, also known as quantum dots, are mesoscopic semiconductors whose physical dimensions lie in between those of bulk solids and individual molecules. As a result of their size, these nano-particles exhibit fascinating physical and chemical behavior.

Our lab is interested in the wet-chemical synthesis of semiconductor nanostructures, as well as their unique size and shape-dependent physical and chemical properties. We are also interested in studying their behavior in a chemical controlled micro-environment, which can be facilitated via the use of microfluidic devices.
