Abstract
An optical tweezers lifting apparatus is provided. The optical tweezers lifting apparatus includes an optical tweezers and a particle-lifting device. The particle-lifting device includes a substrate and a plurality of electrodes that are disposed on the bottom of a flow path in the substrate. When a dielectrophoresis (DEP) solution with a plurality of floating particles is conducted into the flow path and upon those electrodes and a voltage is applied to these electrodes, these particles would be driven by a negative DEP force to move upward to a specific depth in the flow path. Meanwhile, the optical tweezers of the apparatus is selectively focused at the specific depth in the flow path.
