许多血液测试必须在没有细胞物质存在的血浆上进行。在标准的实验室方案中，通过离心法获得纯净的血浆。为了制造小型化的血液传感器，需要一种不同于离心法的分离血浆的方法。我们描述了流体过滤器的设计、制造和测试，以满足这一需求，并具有一些普遍感兴趣的特性。特定设备的结果表明，我们可以很容易地从流体中去除直径为16微米的球体。这种过滤器可以重复使用，可以潜在地去除小至0.1微米的颗粒，并且易于制造。
Many blood tests must be performed on plasma without cellular matter present. Ln the standard laboratory protocol, pure plasma is obtained through centrifugation. in order to produce a miniaturized blood sensor, a method to separate plasma other than centrifugation is needed. We describe the design, fabrication, and testing of a fluid filter that fulfils this need, and also has some features of general interest. Results from a particular device show that we can easily remove 16 mu m diameter spheres from the fluid. This filter can be reusable, can potentially remove particles as small as 0.1 mu m, and is easily fabricated.
