Abstract

We present the on-chip multi-sorting using high-speed flow control with high-accuracy. The speed and accuracy of flow control are critical to throughput of sorting and the number of sorting branches. However, it was difficult in previous researches to achieve both of high-speed and high-accuracy flow control for the high-throughput multi-sorting. By utilizing the on-chip deal membrane pumps driven by the piezoelectric actuators, we succeeded in accurately controlling the flow containing the target particle with high-accuracy of 3.0 µm in 200-µm-width microchannel. In addition, we achieved the high-speed flow control with the response time of within 50 µs. We demonstrated the on-chip multi-sorting with 11-branches. As the result, we succeeded in multi-sorting with the success rate of 88 % at least.
