Figure 4

Extracted video frames showing laser actuated rotation of an optically trapped silicon nanomembrane. The silicon membrane is held in place using a single static trap directed at the attached functionalized bead. Frames (a) through (c) show membrane rotation about this coordinate using a second dynamic optical trap. The second trap does not directly interact with the nanomembrane but instead uses the optical scattering force to direct its motion. This indirect approach prevents damage to the strongly scattering silicon object.
