  • (a) providing a device comprising a microdroplet transport channel, said channel i) having one or more hydrophobic regions and ii) in communication with a gas source;

    (b) introducing liquid into said channel under conditions such that said liquid stops at one of said hydrophobic regions so as to define i) a source of liquid microdroplets disposed within said channel and ii) a liquid abutting hydrophobic region; and

    (c) separating a discrete amount of liquid from said source of liquid microdroplets using gas from said gas source under conditions such that a microdroplet of defined size i) comes in contact with, and ii) moves over, said liquid-abutting hydrophobic region.
