3D MICROFABRICATION AND MIXING PHENOMENA IN MICROFLUIDICS

Abstract

Microfluidic devicesare currently replacing their macroscopic counterparts in many applications.Controlling the mass transport in the microchannels mostly depends on materialused and channel geometry is the key parameter to improve flows speed, reactionsensitivity and surface robustness. As the flow type in the microfluidicchannels is laminar, micro-mixers have been using to provide semi-turbulentflow inside the microchannels. In this study, microfluidic molds werefabricated by using 3D printing method and mixing phenomena was observed indifferent microplatforms with and without micro-mixer geometries to understandthe underlying diffusion mechanism, which causes to mixing phenomena in themicrochannel.
