Open digital microfluidic chips with a single plate, driven by electrowetting force on dielectrics (EWOD), were fabricated. An array of patterned electrodes was printed on a paper substrate in the inkjet printing method with carbon nanotube (CNT) ink. Patterning electrodes on planar substrates can never be achieved just in one-step for common photolithographic method which demands the successive multi-processes, such as spin coating, baking, expose and develop. These high cost procedures also need using hazardous chemicals and complicate equipments. Using an inkjet printer, the CNT solution has been easily printed out the designed patterning electrodes on paper only in one-step in sub-millimeter scale with good conductivity. The performances of CNT electrodes, when they are applied in electrowetting and in moving a liquid drop on a opened microfluidic chip, were highly comparable to that of the photoresist patterned electrodes. Based on these results we constructed the flexible opened chips on paper substrates for merging and moving the liquid drop samples.
