Do It Your Self Electrowetting Coating for OpenDrop Cartridge

This simple procedure to coat an electrode array using readily available materials was developed over the years in the Digital Biology Community. The method is ideal to learn about electrowetting and does not need any specific equipment. The procedure works to make an open or “topless” electrowetting configuration with the droplets sitting openly on the cartridge without top cover glass. The little spherical droplets dancing around are a true eye-catcher. This makes it ideal for workshops, education and technology demonstrations.
Circuit board with electrode array compatible with OpenDrop Version 4.
