3D MICROFABRICATION AND MIXING PHENOMENA IN MICROFLUIDICS

Microfluidic devices are currently replacing their macroscopic counterparts in many applications. Controlling the mass transport in the microchannels mostly depends on material used and channel geometry is the key parameter to improve flows speed, reaction sensitivity and surface robustness. As the flow type in the microfluidic channels is laminar, micro-mixers have been using to provide semi-turbulent flow inside the microchannels. In this study, microfluidic molds were fabricated by using 3D printing method and mixing phenomena was observed in different microplatforms with and without micro-mixer geometries to understand the underlying diffusion mechanism, which causes to mixing phenomena in the microchannel
