Abstract:
1. A method for analyzing interactions between reagents and target substances, comprising: (a) providing at least three primary fluid flows in substantially the same plane, said primary fluid flows all being adjacent simultaneous substantially parallel fluid flows, wherein said primary fluid flows are contained in a chamber having at least one internal cross-sectional dimension of less than 1000 microns, and wherein at least one of said primary fluid flows comprises a target substance and is flanked on each side by a primary fluid flow, and wherein the primary fluid flows flanking said target-comprising primary fluid flow comprise, respectively, a first reagent and a second reagent capable of reacting with the target substance; (b) providing one or more secondary fluid flows, said secondary fluid flow(s) located in a plane that is substantially orthogonal to the plane of said primary fluid flows, wherein each of said secondary fluid flows is introduced into one of said primary fluid flows comprising a target substance, and wherein at least one secondary fluid flow comprises a third reagent capable of reacting with the target substance; and (c) monitoring reactions between reagents and target substances.
