Abstract: By coupling electromagnetic field to coherent oscillation of free electrons, surface plasmons can concentrate light into nanoscale beyond the free-space diffraction limit. We exploit plasmonic nanotechnology to manipulate light, mass and energy at the nanoscale for emerging applications. Herein, I present our progress in three areas: (I) user-friendly low-power optothermal manipulations of colloidal particles and biological cells [1-10]; (II) plasmon-induced resonant energy transfer and hot-electron injection at metal-molecule and metal-semiconductor hybrids [11-16]; and (III) moire metasurfaces and metamaterials [17-21].
