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.
目标材料结晶的高通量筛选是通过将目标材料溶液同时引入微型流体设备的多个腔室来实现的。然后操纵微型流体设备来改变腔室中的溶液条件,从而同时提供大量的结晶环境。对变化的溶液条件的控制可采用多种技术,包括但不限于通过体积排阻将结晶剂计量到腔室中,根据微制造结构的尺寸决定结晶剂的体积,或将样品和结晶剂跨通道注入由相交的正交流道定义的结点阵列中。
