Abstract

This paper reports a simple syringe-assisted pumping unit for traditional microfluidic networks. The proposed design does not require pre-designed vacuum chambers, the multiple pumps can be integrated into one device and a constant flow rate can be achieved using the pumps. The proposed pump can be used by bonding to the outlet ports of a microchip for triggering the sample. Users can choose proper pumping modules for their microfluidic networks. A constant flow with a rate ranging from 1.8 nl/s to 4.4 nl/s was achieved by adjusting air diffusion area of the PDMS wall. As a proof of concept, two samples micro-mixing was demonstrated using dye water.
