Fabrication of Micro-Mixer for Life Sciences Applications (original) (raw)

Micro mixer is an important component in biomedical application, because many bio-molecular processes require rapid and complete mixing. Due to the small channel size of a micro fluidic system, the flow is usually laminar, and so the mixing of fluids in the system remains a challenge. Technologies that currently exist to address the technological aspects of point of care test development is microfluidic and this device have the potential and the toolset to make many POC diagnostic systems possible. Microfluidic transportation and effective mixing are of importance. Hence, the study demostrated an in-house fabrication and characterization of passive flow driven with low Reynolds number of 76 using capillary phenomena. The fabricated device was tested using two samples with different colours for uniform mixing. The uniform concentration of 3mole/g at 76% total length of the micromixer at a point where sensing elements are expected to be placed is obtained.
