الوصف: A novel optically-induced dielectrophoretic (ODEP) device incorporating a gold nanofilm is proposed for the manipulation of microparticles. The electrokinetic phenomena induced under different optical radial images are investigated both numerically and experimentally. The results show that the gold nanofilm not only extends the operating frequency of the ODEP device, but also prompts a change in the direction of the DEP force from the outward direction to the inward direction at high frequencies. Consequently, particle concentration can be achieved in the high frequency range. Overall, the proposed device provides a bi-directional and velocity/force-controllable approach for the manipulation of microparticles in ODEP applications.
