Universal Fluid Microdrop Ejector


Stanford Reference:

97-108


Abstract


Stanford researchers have developed a patented, economical fluid droplet ejector that is capable of varying the vertical and horizontal inter-droplet spacing of a two-dimensional droplet array in real time. This universal design is compatible for a wide variety of fluids because it can be manufactured with a material and process that enables the device to be both chemically inert and biologically sterile. It also utilizes a micro-machined aperture and thermally fused components for easy of manufacturing and to enable mass production. The ejector can produce droplets from 5 to 100 microns in diameter at a rate up to several hundred hertz. The issued patent details the design's suitability for several physical, chemical and biological applications including: droplet analysis experiments, aerosol characterization, material deposition and cell-sorting applications.
