Surface plasmons, which are coherent oscillations of delocalized electrons at the interface of two materials, can concentrate and manipulate light at the nanoscale. We exploit unique optical, thermal, mechanical, electrical and chemical properties associated with surface plasmons to innovate a wide range of optical nanotechnologies in health, energy, manufacturing and national security. I present our progress in three areas: (1) multiband and chiral optical manipulations with moire metasurfaces and metamaterials, (2) versatile low-power opto-thermal manipulations of colloidal particles, biological cells and molecules, and (3) plasmonic control of energy transfer at complex interfaces. Applications in artificial matter, colloidal devices, rewritable nanophotonics, solar water splitting, catalysis, surface-enhanced molecular spectroscopy, sensing, cellular biology, molecular biology, pharmaceutics, oil industry, and water treatment are demonstrated.
