We design and synthesize functional plasmonic nanostructures from simple nanospheres and nanocubes to multicomponent nanoparticles, nanogap nanoparticles and mechanically interlocked nanostructures.

We characterize and utilize plasmonic nanostructures for surface-enhanced Raman spectroscopy (SERS), metal-enhanced fluorescence (MEF), photothermal property and other plasmonics-related properties and functions.

We develop plasmonic nanoprobes for biosensing, bioimaging, biocomputing, nanomachine and therapeutic applications.
