A target object can be manipulated by radiation force. Here we explain the optical transportation of semiconductor nanoparticles using its resonant enhancement. Since semiconductor nanoparticles have discrete energy level structures owing to the quantum confinement effect, the radiation force is strongly enhanced when the incoming light resonantly excites the semiconductor nanoparticles. This enhancement enables us to efficiently manipulate and sort the nanoparticles with resonant radiation force.
