We demonstrated all-dielectric nanostructures which exhibited directional Fano resonances, reversed optical binding force, and field-enhancement along with ultra-low heat generation. Optical interactions between magnetic dipole (MD) and electric dipole (ED) modes in the dielectric nanostructures played crucial roles in the unique optical characteristics, especially in damage-free field enhanced Raman spectroscopy.
