Abstract
High throughput screening of crystallization of a target material is accomplished by simultaneously introducing a solution of the target material into a plurality of chambers of a microfabricated fluidic device. The microfabricated fluidic device is then manipulated to vary the solution condition in the chambers, thereby simultaneously providing a large number of crystallization environments. Control over changed solution conditions may result from a variety of techniques, including but not limited to metering volumes of crystallizing agent into the chamber by volume exclusion, by entrapment of volumes of crystallizing agent determined by the dimensions of the microfabricated structure, or by cross-channel injection of sample and crystallizing agent into an array of junctions defined by intersecting orthogonal flow channels.

19. A method for mixing a first reactant and a second reactant comprising:
-
providing a microfabricated elastomeric block having a chamber therein;
introducing into the chamber a volume of the first reactant; and
introducing a volume of the second reactant into the chamber by entrapping a volume of the second reactant proximate to the chamber and then opening an elastomeric valve positioned between the chamber and the second reactant to allow entry of the second reactant into the chamber. - View Dependent Claims (23, 24, 33)

39. A system for mixing a first reactant and a second reactant, the system comprising:
-
a microfabricated elastomeric structure having a chamber therein;
a volume of a first reactant contained within the chamber; and
a volume of a second reactant entrapped proximate to the chamber and separated from the chamber by an elastomeric valve, wherein, in use, opening of the valve allows mixing of the first reactant and the second reactant. - View Dependent Claims (40, 41, 42, 43)
