Paper Abstract

We report the development of a high efficiency magnetic microfluidic mixer based on a novel 3D impellor-shaped ferromagnetic micro-stirrer bar. The 3D impellor-shaped micro-stirrer bar with 31.6º inclined angle is fabricated using titled (55º) SU-8 exposure technique. The 3-D inclined micro-stirrer bar causes 3-D perturbation of fluids resulting in rapid mixing in microscale. When compared with a vertical straight sidewall micro-stirrer bar, approximately 20% of mixing efficiency enhancement is achieved.
