| contents | We demonstrate that a set of microfabricated electrodes can be coupled to a commercial optical tweezers device, implementing a hybrid electro-optical trap with multiple functionalities to manipulate micro/nanoparticles in suspension. Our design allows us to simultaneously trap tens of particles in a single potential well generated in the low electric field region of the electrode arrangement, taking advantage of negative dielectrophoresis. Together with the optical tweezers, we show that the hybrid scheme allows enhanced manipulation capabilities, including controlled loading and accumulation in the dielectrophoretic trap from the optical tweezers, selectivity, and tracking of the individual trajectories of trapped particles. |
