Incorporating resonant optical properties of metal nanostructures into nanoscale applications such as ultrahigh density storage devices, nanoelectronics, and nanophotonics has gained considerable interest within the last years. Recent advances in hybrid and molecular plasmonics are presented. The approach relies on near-field energy transfer between metal nanoparticles and other molecular material, and is not diffraction-limited. We will see that optical nanosources supported by metal nanoparticles can be used for controlling/triggering photochemical and photo physical processes involving photons, charges and motion transfers at the nanoscale. In particular, three examples will be presented and commented: free radical photopolymerization, photo isomerization and nanoscale strong coupling. These examples open new routes including optical near-field photography of ultra confined fields, mode hybridizing in single nanoparticles, molecular optical nanomotors, and new anisotropic nanoemitters.
