Photonics, plasmonics and novel materials

Our lab develops novel devices and applications using state-of the art nanoplasmonic and photonic sensors. We also develop new materials to expand the utility of these sensors. Our vision is to bridge the fields of engineering and medicine for next-generation diagnostic technologies. Based on physics and basic in nature, our ultimate goal is clinical translation.

Nano-plasmonic sensors

In the past, we have developed nanoplasmonic sensing systems (nPLEX/NPS) for exosome analysis in cancer. Ongoing projects are in the fields of highly multiplexed exosome analysis as well as for single molecule analysis.

The nPLEX sensor was highlighted as one of the greatest hits among 20 years of Nature Biotechnology biomedical research.
