FLUID FLOW CONTOUR CONTROL USING FLOW RESISTANCE

摘要

A micro-fluidic device and a method of use are disclosed. The device includes a micro-channel with an inlet port at a first end and an outlet port at a second end. A first fluid, such as air or liquid or both, is disposed in the micro-channel. A focusing structure extends into the micro-channel, whereby when a pulse of a second fluid is introduced to the channel, the pulse advances adjacent sides of the micro-channel at a faster rate than would occur without the focusing structure.
