Smart Nanoplasmonics for Biology and Chemistry

The nanometer scale is where the chemistry, biology, and materials sciences converge. The subtopic of nanoplasmonics deals with localization and manipulation of light in a nanometer volume. The key material component for plasmonics is metals. The optical properties of metal nanoparticles have been an object of fascination since ancient times. When light interacts with a metal nanoparticle (for example a gold colloid in a stained church window), collective oscillations of conduction electrons known as particle plasmons are excited.

Functionalized metallic nanoparticle assemblies with well-designed configurations enable intriguing optical properties and offer a helpful hand for understanding profound biochemical behavior. Our group focuses on developing sophisticated and smart plasmonic nanostructures for
