摘要

本文综述了小型化生化分析系统的组成,重点讨论了微机械金属移液阵列(MPA)和微机械电场流分馏系统(μ-EFFF)。MPA是从硅衬底延伸出来的中空金属移液器阵列。这些阵列用于在pl到μl范围内的样品的宏观尺度空间操作。μ-EFFF系统由微机械流道和集成电极组成,用于静电作用。该系统用于生物分子和胶体的分离和分析。介绍了MPA和μ-EFFF的设计、制作和表征。此外,还讨论了利用微机电一体化技术实现各部件的集成。

Integrated micromachined components for biological analysis systems
In this paper, we provide an overview of miniaturized biochemical analysis system components and specifically discuss the micromachined metallic pipette arrays (MPA) and the micromachined electrical field-flow fractionation system (μ-EFFF). The MPA are arrays of hollow metallic pipettes extending from a silicon substrate. These arrays are used in macroscale spatial manipulation of samples in the pl to μl range. The μ-EFFF system is composed of a micromachined flow channel with integrated electrodes for application of static electric fields. The system is used for separation and analysis of biological molecules and colloids. The design, fabrication, and characterization of the MPA and the μ-EFFF are described. In addition, the integration of the components using micromechatronics technologies is discussed.
