This paper presents our discovery that self-rotation of Melan-a pigment cells can be induced by applying appropriate optical dielectrophoretic (ODEP) parameters. Under optically induced DEP force, which is generated by specific optical electrode patterns and with a band-width of AC bias frequencies, Melan-a cells can be trapped or repelled away from the optical electrodes. In addition, the self-rotation...
We discuss in this paper a novel observation of self-induced rotational motion of pigmented biological cells in a dielectrophoretic force field. The experimental platform for our work is basically a microfluidic system fabricated with Au microelectrode on the glass substrate with PDMS microchannel irreversibly bonded on top of it. To investigate the cell movement in this microfluidic system due to...
