Fluid Mixing for Low‐Power ‘Digital Microfluidics’ Using Electroactive Molecular Monolayers

An array of planar indium‐tin oxide electrodes for droplets actuation based on a self‐assembled monolayer terminated with a switchable electroactive anthraquinone group is fabricated. The electrodes are integrated in a microfluidic device to perform mixing and dispensing at sub‐nanoliter scale. Vehiculation of cells across microfluidic compartments is further demonstrated.
