OpenDrop is a modular, open source digital microfludics platform for research purposes. The device uses recent electro-wetting technology to control small droplets of liquids. Potential applications are lab on a chip devices for automating processes of digital biology. The device features a high voltage pump powered by USB-C, is reprogrammable and arduino compatible. An open source PC software based on Processing is available.
The electrowetting cartridge is based on a printed circuit board that holds 128 individual electrodes. The individual electrodes are connected to the backside of the circuit board through vertical interconnects (VIAs) and linked to the cartridge connector on the back.
The project was published in the scientific paper: OpenDrop: An Integrated Do-It-Yourself Platform for Personal Use of Biochips
