    摘要: Provided is a method of isolating and purifying nucleic acids using an immobilized hydrogel or polyethylene glycol (PEG)-hydrogel copolymer. The method includes: immobilizing a functional group-containing hydrogel or PEG-hydrogel copolymer on a substrate; adding a mixed sample solution containing a salt and nucleic acids to the hydrogel- or PEG-hydrogel copolymer-immobilized substrate to bind the nucleic acids to the hydrogel or the PEG-hydrogel copolymer; washing the nucleic acid-bound hydrogel or PEG-hydrogel copolymer; and eluting the nucleic acids from the hydrogel or the PEG-hydrogel copolymer using an elution solvent. Therefore, binding and elution of nucleic acids can be performed even with no addition of a separate chemical substance, and an effect on a subsequent process such as PCR can be minimized. Furthermore, the amount and intensity for binding nucleic acids can be adjusted according to PEG concentration, and the presence of a hydrogel compound on a substrate enables patterning.

    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.
