  • Patent number: 7412990
    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.

  • Patent number: 7183056
    Abstract: The present invention is directed to an improved multiplex PCR method for obtaining at least two PCR products from one PCR solution. In the multiplex PCR method for having at least two DNA amplified products from a sample positioned in a PCR equipment, the object of the present invention is to provide a novel multiplex PCR method characterized in that a primer annealing temperature and an extension time be changed per cycle with constant periods. When a multiplex PCR is performed in accordance with the present invention, limitations in determining PCR conditions due to a various sizes of PCR products or dimers caused by primers can be eliminated, and time and efforts required for determining the PCR conditions to various samples can also be reduced. Further, not only refined DNAs like cDNA, genomic DNA, vector, etc, but blood can be directly used as a multiplex PCR sample, and PCR amplification reaction can be performed even with a sample having the smallest amounts.

  • Patent number: 6901963
    Abstract: Provided is a micro fluidic device that can control a flow time of micro fluid by using a capillary phenomenon. The micro fluidic device includes: a flow channel for flowing fluid, the flow channel being formed between a top substrate and a bottom substrate or between a top substrate, a bottom substrate, and a middle substrate; a flow blocking surface for stopping a flow of the fluid in the flow channel temporarily; and a hump for delaying the flow formed in the line of continuity with the flow blocking surface. The micro fluidic device of the present research can control the flow time in a simple manner.
