    Open-Top Optofluidics Architecture Adds Flexibility, Increases Droplet Speeds

    Article obtained from Photonics RSS Feed.

    Optoelectrowetting (OEW) is a digital optofluidic technology based on the principles of light-controlled electrowetting that enables the actuation and manipulation of discrete droplets of liquid. In traditional OEW devices, droplets are sandwiched between a bottom active OEW substrate and a top layer ground electrode substrate. As a result, any droplet-dispensing or -extraction techniques must be integrated from the side openings.

    In research published by the University of California, Berkeley (UC Berkeley), a single-sided, coplanar OEW device that features a conductive metal mesh grid integrated with the device surface to allow droplets to be exposed from above. Droplets can still move freely around the 2D device surface, but are…
