MICROFLUIDIC DEVICE CAPABLE OF EQUALIZING FLOW OF MULTIPLE MICROFLUIDS IN CHAMBER, AND MICROFLUIDIC NETWORK EMPLOYING THE SAME
First Claim
1. A microfluidic device capable of equalizing flow of multiple microfluids in a chamber, comprising:
- a plurality of flow channels that are formed between an upper substrate and a lower substrate to transfer the microfluids and include inlets for injecting the microfluids in one side and fluid stopping surfaces for stopping the flow of the microfluids in the other side;
a pressure controlling flow channel for removing a pressure difference between the microfluids injected into the flow channels, respectively, and connecting the inlets;
a fluid converging part for converging the microfluids that are transferred passing through the fluid stopping surfaces, respectively; and
a chamber composed of hydrophilic surfaces and hydrophobic surfaces disposed alternately in a direction that the microfluids flow so that the microfluids joining in the fluid converging part flow in parallel and equal, the hydrophilic surfaces and the hydrophobic surfaces having a predetermined width.

Abstract
Provided are a microfluidic device and a microfluidic network formed by connecting such microfluidic devices. The microfluidic device can equalize the flow of multiple microfluids in a chamber in parallel to thereby have an equal flow rate when the microfluids transferred through different flow channels join in the chamber having a changing cross-sectional area. The microfluidic device includes: multiple flow channels formed between an upper substrate and a lower substrate to transfer the microfluids and including inlets for injecting the microfluids in one side and fluid stopping surfaces for stopping the flow of the microfluids in the other side; a pressure controlling flow channel for removing a pressure difference between the microfluids; a fluid converging part for converging the microfluids; and a chamber composed of hydrophilic surfaces and hydrophobic surfaces disposed alternately in a flow direction so that the microfluids join and flow in parallel and equal.
