Abstract

Micromixer has been studied for several years. In this paper we have attempted to design and develop a new type of combinatorial chaotic and serpentine micromixer (CSC) that is compatible with the microfabrication process of polydimethylsiloxane (PDMS). We visualize the mixing of the fabricated CSC micromixer. A mixing experiment was performed using the Rhodamine B with Micro-LIF. Such a new and novel micro-mixer is simple to fabricate and easy to use. The micromixer is characterized and visualized with the help of the Micro-LIF technique. The new micromixer will e further applied to lab-on-chip device. The mixing capability of this mixer is about 30-33%.
