Surface Modification for Digital Microfluidic Devices

Shahrestani, Seyedeh Niko 22 September 2009 (has links)
Digital Microfluidics (DMF) is a new field of science and technology that introduces movement of nanoliter to microliter size droplets on patterned electrodes. Droplets can be moved, dispensed, merged, and split on devices. Sequential chemical reaction, and DNA extraction are examples of biological applications of DMF. In this thesis, sol-gel technology has been used as a coating method for thin film fabrication. Sol-gel is suitable for coating thin films with flexible shapes. BaTiO3 was used as a dielectric material for coating the insulator layer of the device. The material was spin coated on glass substrates. Devices were coated spinning at 500 rpm for 45 s, and annealed at 600 °C for 2hrs. The ceramic layer obtained, had a thickness of ~1 µm and average roughness of 60 nm. Nanoliter size droplets of water of ~400 nl were moved on the surface of the devices applying minimum voltage of 30 Volts.
