    • A method for casting-in-place composite and/or non-filled structures which are useful as sorptive or reactive media or for size-based separations. Any particular housing size or configuration can be used, and the inclusion of a large amount of adsorptive particles in polymer is achieved while still maintaining the membrane three dimensional structure. In a first preferred embodiment, the composite structures comprise particles entrapped within a porous polymeric substrate, and are cast in-place into a housing such as a pipette tip, thereby providing an effective platform for micromass handling. With the appropriate selection of particle chemistry, virtually any separation or purification operation can be conducted, including selective bind/elute chromatography operations, on sample mass loads less than 1 microgram in volumes of a few microliters, as well as larger mass loads' and volumes. The present invention also encompasses the composite structures as well as sample preparation devices containing the same. In a second preferred embodiment, self-retaining, self-supporting structures are cast in situ in a suitable housing and can be used for size-based separations wherein the cast structure acts as a semi-permeable barrier. The present invention also encompasses these structures as well as housings containing these structures.
    • 用于现浇复合和/或非填充结构的方法,其可用作吸附或反应介质或基于尺寸的分离。 可以使用任何特定的壳体尺寸或构型,并且在保持膜三维结构的同时实现在聚合物中包含大量吸附颗粒。 在第一优选实施方案中,复合结构包括捕获在多孔聚合物基底内的颗粒,并且被放置在诸如移液管尖端的壳体中,从而为微粒处理提供有效的平台。 通过适当的颗粒化学选择,可以进行任何分离或纯化操作,包括选择性结合/洗脱色谱操作,样品质量负载小于1微克体积的几微升,以及较大的质量负载和体积 。 本发明还包括复合结构以及含有该结构的样品制备装置。 在第二优选实施例中,自固位自支撑结构在合适的壳体中原位铸造,并且可用于基于尺寸的间隔,其中铸造结构用作半渗透屏障。 本发明还包括这些结构以及包含这些结构的壳体。
