Abstract
A microfabricated droplet dispensing structure is described, which may include a MEMS microfluidic fluidic valve, configured to open and close a microfluidic channel. The opening and closing of the valve may separate a target particle and a bead from a sample stream, and direct these two particle into a single droplet formed at the edge of the substrate. The droplet may then be encased in a sheath flow of an immiscible fluid.
