The authors demonstrate that it is possible to manipulate helical superstructures composed of self-assembled chiral lipids by dielectrophoresis while preserving the shape of the superstructures. Alignment and migration of the helical fibers were only observed for an applied ac field of 1 kHz-1 MHz. The structural and phys. properties of the helical fibers were preserved even under a.c. elec. fields. This is the first report on the manipulation of a helical mol. assembly wherein the original properties of the assembly remained unchanged even after manipulation.
