基于层流效应的被动式颗粒分离微流控方法研究
Study on passive microfluidic method for particle separation based on laminar effect
摘要
Abstract
The separation of microparticles widely exists in the energy,chemical,and biomedical fields.Based on the laminar effect,a new microfluidic method was proposed and investigated with the experiment by considering different flow conditions,properties of fluids and particles.The result shows that the present method enables the efficient separation of microparticles with different sizes.The flow rate ratio and the size difference between particles significantly influence the separation performance.The separation efficiency and the purity increase with the increase of the flow rate ratio and the size difference between particles.However,the total flow rate and the property of the fluid have almost no effect on the particle separation.With the advantages of simple structure,easy operation,high efficiency and wide applicability,the present method would have great potentials in practical applications.关键词
