Real-time Flow-rate Control System for Cell Analysis

On-chip cell analysis is an important issue for microtechnology research. One approach to controlling the fluid flow in microfluidic devices for cell analysis is to use syringe pumps. However, it is difficult to control the actual flow rate in a microfluidic device because of the difficulty of placing flow rate sensors in the device. In this work, we developed a real-time flow-rate control system that uses syringe pumps and high-speed vision to measure the actual fluid flow in microfluidic devices. The developed flow-rate control system was verified through experiments on microparticle velocity control and microparticle sorting.
