Microfluidic device and method of manufacturing the same and sensor incorporating the same
Abstract:
The present invention provides a microfluidic device, for instance for molecular sieving or for detecting a target substance in a sample fluid. The device comprises a first substrate (120) having a substantially flat first surface that is provided with first recesses (124), and a second substrate (128) having a substantially flat second surface that is provided with second recesses (130). At least some of the first recesses are filled with a porous material (114). Alternate first recesses and second recesses form a meandering channel for a sample fluid. The second recesses may be filled with a further porous material. In an embodiment, a capture substance for binding a target substance is arranged in or on the porous material.
Abstract(Chinese):

本发明提供了微流体装置，例如用于分子筛或用于检测样品流体中的目标物质。 该装置包括具有基本平坦的第一表面的第一基底（120），第一基底具有第一凹槽（124），第二基底（128）具有基本平坦的第二表面，该第二基底具有第二凹槽（130）。 至少一些第一凹部填充有多孔材料（114）。 替代的第一凹槽和第二凹槽形成用于样品流体的曲折通道。 第二凹部可以被另外的多孔材料填充。 在一个实施方案中，用于结合目标物质的捕获物质被布置在多孔材料中或其上。
