MULTISTAGE DIELECTROPHORETIC SEPARATION CHIP, ITS APPLICATION TO MICROFLUIDIC SYSTEM FOR TOTAL BLOOD CELL ANALYSIS, AND ASSAYING METHOD OF THE TOTAL BLOOD CELL USING THEREOF

摘要

The present invention relates to a multi-electrophoretic-based microfluidic chip, a microfluidic system for whole blood analysis and a whole blood analysis method employing the same, and more specifically, a cell or microparticle injection unit (1); A bent microfluidic channel portion composed of at least one or more for selectively deflecting the injected cells or microparticles by dielectrophoresis force and separating them into a plurality of cells or microparticles; A microexpansion channel part 3 for separating and separating the deflected cell particles; And multistage dielectrophoresis (MSDEP) -based microfluidic chips, microfluidic systems for whole blood analysis, and the multi-electrophoresis based on the number of discharge parts (4) to (7) as many as the number of cell particles. As for the whole blood analysis method, according to the present invention, unlike the whole blood analysis method which is conventionally performed in a first-line hospital, etc., the cell recovery rate is high and the advantage of being able to quickly and accurately and conveniently characterize whole blood from a very small amount of blood (nl) Have;Multiple Dielectrophoretic Separation Chips, Trapezoidal Electrode Arrays, Micro Expansion Channels, Separation-Based Bioparticle Analysis Systems
