Abstract
Provided is a microfluidic control device and method for controlling the microfluid, and a fine amount of fluid is controlled even with natural fluid flow and solution injection, wherein a pressure barrier of a capillary is removed by a surface tension change resulted from the solution injection to thereby obtain transport, interflow, mixing, and time delay of the microfluid, and to detail this, solution is injected to meet the boundary surface of the stopped fluid when the fluid is stopped by the stop valve, so that a function of the stop valve is removed to obtain the transport, interflow, and mixing of the fluid, and the method for controlling the microfluid may be applied to the microfluidic control device for biochemical reaction, and it uses only the capillary force change resulted from solution injection to thereby have its structure simplified.
