Localized surface plasmon resonance arising from the interactions of light with gold nanostructures can confine photons in the nanometer scale beyond diffraction limit. Especially, gap-mode localized surface plasmon resonance produces high intense and steep EM fields in the nanometer scale. By confining photons into the nano-space, the spatial mismatching between the wave function of clusters and the wavelength of light is dissociated, resulting in tremendous enhancement of light-matter interactions. Plasmonic optical trapping increases local concentration in the nanogap, eventually leading to crystallization. We here present chiral crystallization of sodium chlorate and control its crystal chirality by plasmonic optical trapping with circularly-polarized light.
