This paper describes the performance of organic droplet mixing using a digital microfluidic (DMF) device. DMF devices have been applied to the dispensation and transportation of aqueous droplets using electrostatic forces and are suitable for quantitative analysis that requires rapid mixing and reactions. However, DMF devices have not been applied to organic materials. We revealed the behavior of a manipulated organic droplet exposed to different voltages. We expect this device to be a powerful tool for high throughput screening of organic materials.
