Abstract
A method and device for generating droplets of immiscible fluids are provided. Extremely fine droplets may be generated, on the order of 1 picoliter or less, using focused acoustic energy to eject the droplets from a reservoir containing two or more immiscible fluids. Optionally, the droplets may be ejected onto discrete sites on a substrate surface so as to form an array thereon.
