Abstract
Electrowetting on a dielectric (EWOD) is a phenomenon that, along with other microfluidic devices, offers a revolutionary approach to modern medicine. Microfluidic devices, such as EWOD, enable precise control of liquid droplets on microscale platforms. Downsizing common laboratory diagnostic methods reduces the need for reagents and patient samples, as well as costs and time, leading to portable devices that deliver rapid results. Despite its potential, EWOD technology still faces challenges related to device efficiency and reliability. Exploring the relationship between surface properties and electrowetting performance is crucial for enhancing device functionality. This study aims to evaluate electrowetting devices using atomic force microscopy to analyze surface properties at the nanoscale. Experiments are conducted to determine measurement methods for the surface topography of electrowetting devices, as well as to develop techniques for measuring adhesive forces and the hydrophobicity of the device top coating
