Extracted video frames showing XY translation of an optically trapped silicon nanomembrane. Frames (a) through (f) show the trapped membrane moved along a circular path in a single imaging plane. The path was defined using a custom built LabVIEW program to control the output of a spatial light modulator. The trapped membrane was translated along the path using discrete angular steps of 2.5°. When moving in a circular fashion, we see rotation of the nanomembrane around the trapped bead, stemming from the step-by-step directional change of fluid drag forces acting on the nanomembrane. Similar rotation is not observed when moving the nanomembrane in a straight line over long distances.
