Synthesis and Functionalization of Metal Nanoparticles

This project is ongoing.

Nanoparticles of novel metals (e.g. Au and Ag) support localized surface plasmon resonances (LSPRs), the light-coupled coherent oscillation of free electrons confined in the particles. Due to the capability of LSPRs in concentrating light at the nanoscale, metal nanoparticles have a broad range of applications from high-efficient solar energy conversion to ultra-sensitive biosensors. LSPRs and their applications depend on the shapes, sizes, and surface modifications of metal nanoparticles. In this project, we aim to synthesize Au and Ag nanoparticles of various geometries and topology with precisely tailorable LSPRs. We will also develop assembly and measurement strategies for functionalization of nanoparticle surfaces with molecular switches for the developments of novel nanomaterials and nanodevices.

I'M INTERESTED IN THIS PROJECT. WHAT SHOULD I DO NEXT?

The Office of Undergraduate Research recommends that you attend an info session or advising before contacting faculty members or project contacts about research opportunities. We'll cover the steps to get involved, tips for contacting faculty, funding possibilities, and options for course credit. Once you have attended an Office of Undergraduate Research info session or spoken to an advisor, you can use the "Who to contact" details for this project to get in touch with the project leader and express your interest in getting involved.
