First we briefly summarize the existing schemes and their range of applicabilities. In a circularly polarized optical trap, birefringent microparticles are seen to rotate [2, 3], Microobjects, when trapped in a spiral optical pattern, have also been observed to rotate [4-6]. Rotations of specifically fabricated rather big rotors under an optical tiap have been 

In addition to this, it is noteworthy that the direction of the rotational motion was not same for all the rotors. Though a rotor always rotated in a particular direction, both right-handed and left-handed rotations were observed with equal probability in randomly selected nanorotors.
