Integrated Finger-Powered Microfluidic Pumps for Point-of-Care Diagnostics

This project aims for developing a new 'human-powered' microfluidic system for point-of-care diagnostics applications. Chip-based microfluidics offers a promising platform for biological studies; however, bulky and expensive equipments such as syringe pumps limit the application. To minimize the total setup, we propose an alternative 'human-powered' fluid pumping device. Pressure generated by human finger works as a major power source to pump fluids into microfluidic devices without any electricity. As we use common softlithography fabrication process, our system can be easily integrated with existing microfluidic systems such as microdroplet generator or cell encapsulating system. In addition, it is possible, in the future, to apply injection molding to significantly reduce the cost for industrial applications. Our portable, easy-to-operate system offers an effective method for pumping fluid into microfluidic devices for expanding biological applications such as drug screening or point-of-care diagnostics.
