title: Fast, active droplet interaction: coalescence and reactive mixing controlled by electrowetting on a superhydrophobic surface.
abstract: A novel electrowetting-on-dielectrics (EWOD) device in open planar geometry allows probing of droplet mixing on a superhydrophobic substrate under quasi contact-free conditions. We demonstrate a droplet-based microreactor with integrated convective-flow mixing for the reactive-mixing of CaCl(2)/Na(2)CO(3) solutions. The device provides unique conditions for scattering, spectroscopy and imaging probes requiring an unobstructed droplet-access.
