    摘要: Provided is a method of separating particles, the method comprising: forming a first chamber and a second chamber separated by an interface with a pore, wherein the first and second chambers have electrodes with different polarities; placing particles to which a target biomolecule is bound from particles to which the target biomolecule is not bound in the first chamber; applying a voltage which has the same polarity as that of the target biomolecule to the electrode of the first chamber, and a voltage which has an opposite charge to that of the target biomolecule to the electrode of the second chamber; and translocating only the particles to which the target biomolecule is bound from the first chamber to the second chamber through the pore. Conventionally, the size of a pore is used to separate biomolecules. However, effective separation is difficult to achieve because the manufacture of a pore with a diameter of less than 10 nm, small enough to separate biomolecule, is not easy. Therefore, signal separation and data analysis must be required. However, in the present method, physical movement induced by the charge of biomolecules is used to effectively separate the biomolecules, thus obtaining a high signal to noise ratio. As a result, additional data analysis is not required.

    摘要: A method of sequentially performing concentration and amplification of nucleic acid in a single micro chamber includes: introducing a nucleic acid-containing sample and a solution including a kosmotropic salt to a micro chamber having a hydrophilic interior surface to concentrate the nucleic acid by binding the nucleic acid on the interior surface of the micro chamber; and performing a polymerase chain reaction (PCR) by adding a PCR mixture to the chamber. Since the nucleic acid is reversibly bound to the interior surface of the micro chamber, PCR yield is higher compared with a surface of aluminum oxide in which irreversible binding occurs. In addition, all processes are sequentially performed in a single micro chamber so that the number of samples, consumables, time, and labor for treatment and analysis can be reduced, detection sensitivity can be improved, and risk of sample cross contamination significantly reduced without sample loss by eliminating transporting of the sample. A complete automated system for concentration and amplification of nucleic acid is thus readily provided.
