Abstract

We succeeded in high-speed on-chip mixing by generating the vortex at the localized point in a microstream. We show the evaluation results of the mixing time within 500 micro-seconds which was over 100 times faster than the previous active mixing method. We also performed the concentration control of mixed liquid by combining the flow control of the core-shell focused flow. Furthermore, we applied the technique to the segment-mixing by controlling the mixing period. From these results, we confirmed that the on-demand high-speed mixing was achieved. The proposed method will contribute to analyze not only the chemical reaction but also the response of cells to environmental changes.
