Abstract:
An apparatus for separating target molecules includes a plurality of protruding portions on a first sidewall of a fluid channel to control a flow of a fluid containing the target molecules, and a fluid channel portion having a variable height for separating the target molecules depending on sizes of the target molecules.
Abstract:
Disclosed is a multifunctional microfluidic flow control device. The device includes at least one microfluid injection part, a microfluid channel part and a microfluid discharge part. The microfluid injection part has first and second microfluid injection pathways. The microfluid channel part is connected to the microfluid injection part and has a concavo-convex pattern to control a flow of at least one kind of microfluid injected into the microfluid injection part. The microfluid discharge part is connected to the microfluid channel part so that the microfluid, the flow of which has been controlled, is discharged through the microfluid discharge part.
