A CENTRIFUGATION-ENHANCED HIGH-EFFICIENCY MICRO-FILTER WITH SPIRAL CHANNEL Xu Ji, Wei Wang, Xia Lou, Jianhong Peng, and Zhihong Li National Key Laboratory of Micro/Nano Fabrication Technology Institute of Microelectronics, Peking University, Beijing, 100871, China (Transducers 2007 P.1865~1868) Reporter: Chung-Kuang Chin ( 秦重光 ) Date:1/2/2008 Outline Introduction Principle Numerical Simulations Fabrication Experiments Results Discussion Introduction Micro-filters/Separators -Goal:to separate, remove and pre-concentrate particles from original mixtures . -usually employed prior to analysis in biologic and chemical diagnostic processes. -Classification:Active or Passive Introduction (cont.) Active micro-filters/Separators -運用靜電力、磁力、機械力 、介電泳力(DEP)、光鑷夾(光場)等來完成。 Introduction (cont.) Passive micro-filters/Separators -純粹靠結構設計來過濾或分類。 Principle Numerical Simulations Fabrication Experiments Results Discussion Reference Review: Microfluidics technology for manipulation and analysis of biological cells, Changqing Yi, Cheuk-Wing Li, Shenglin Ji, Mengsu Yang, Analytica Chimica Acta, 2006 Separation of Blood in Microchannel Bends, C.
