Microfabricated droplet dispensor with immiscible fluid and genetic sequencer

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 biological particle containing genomic material, 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, and provided to a downstream workflow. A third microfluidic channel upstream of the valve may add a biologically reactive material to the sample stream.
