  • We develop and apply new optical techniques for manipulation and assembly of colloidal particles. Current applications range from cellular biology and tissue engineering to programmable designer materials. We carry out multiscale measurements of structures, dynamics and functions of the materials to establish the structure-property relationship. Our long-term goals are to develop scalable bottom-up assembly of designer materials for targeted applications and to elucidate how matter organizes in both materials world and life sciences.

  • With the capability of surface plasmons in manipulating light at the nanoscale, molecular plasmonics bridges size mismatch between light and molecules for new optical phenomena and functions. We aim to advance fundamental understanding of molecule-plasmon coupling with single-nanoparticle and single-molecule measurements and to develop novel optical materials and devices for applications. Our recent achievements include rewritable integrated nanophotonics, moire chiral metamaterials, and chiral sensors.

  • We exploit plasmofluidics, which merges light and fluids at the micro/nanoscale, to miniaturize and empower lab on a chip. We focus on developing and applying (i) point-of-care biomedical devices that bring healthcare diagnostics to underserved areas while advancing study in life sciences and (ii) nanofactories that optically assemble designer materials and devices with colloidal particles as building blocks. 

About

We exploit the synergy among nanophotonics, microfluidics, and colloid and surface chemistry to innovate optical technologies in health, energy, manufacturing, and national securityOur mission is to:

  • advance fundamental understanding and control of light-matter interactions at the nanoscale;
  • develop and apply optically active materials, devices and systems;
  • promote interdisciplinary trainings for students to understand and contribute to the multiple fields of engineering, science, and medicine.

We focus on three coordinated research areas
