MICROFLUIDIC PARTICLE ANALYSIS DEVICE

The present invention relates to a microfluidic particle analysis device comprising an inlet and an outlet in fluid communication via a main channel defining a main flow direction from an inlet end toan outlet end, the main channel being defined by a main channel wall extending from the inlet end to the outlet end and having a first cross-sectional dimension in the range of 20um to 120um and a second cross-sectional dimension of at least 100um, the main channel wall at a vertex having an opening extending along the main flow direction and being open to an analysis section having surfaces at an analytical distance in the range of 5um to 50um and a sensor system for detecting a particle. The present invention also relates to a method of using the microfluidic particle analysis device for detecting particles or monitoring the concentration of particles. 本发明涉及一种微流体颗粒分析装置，该微流体颗粒分析装置包括通过限定从入口端到出口端的主流动方向的主通道而处于流体连通的入口和出口，该主通道由从该入口端延伸到该出口端的主通道壁限定并且具有在20μm到120μm范围内的第一截面尺寸和至少100μm的第二截面尺寸，该主通道壁在顶点处具有沿着该主流动方向延伸的开口并且通向分析区
