Provided is a microfluidic control apparatus that includes at least one control means and a microfluidic control chip. When the microfluidic control chip is loaded to the control means, a needle provided to the control means is inserted into a reaction solution storage chamber of the microfluidic control chip, in which the reaction solution storage chamber is sealed with a sealing tape. Thus, fluid connection is easily formed between the microfluidic control chip and the control means without leakage.

The present invention relates to a plasma extraction method in which a complex of a blood cell-specific antibody and a protein having the ability to bind to the Fc region of the antibody is used to induce the agglutination of blood cells in blood, thereby increasing plasma separation efficiency, and to a plasma separation device therefor. According to the method, plasma can be separated from whole blood in high efficiency, and rapid plasma separation is possible, so that rapid diagnosis can be performed even with a small amount of blood.

A method of measuring a critical dimension may include forming an object pattern on a substrate and forming a plurality of reference patterns on the substrate, wherein each of the plurality of reference patterns has a different critical dimension. An optical property of each of the plurality of reference patterns may be measured to provide a respective measured optical property for each of the reference patterns, and an optical property of the object pattern may be measured to provide a measured optical property of the object pattern. The measured optical property of the object pattern may be compared with the measured optical properties of the reference patterns, and a critical dimension of the object pattern may be determined as being the same as the critical dimension of the reference pattern having the measured optical property that is closest to the measured optical property of the object pattern. Related devices are also discussed.
