    • 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.
    • 在单个微室中依次进行核酸的浓缩和扩增的方法包括:将含核酸的样品和包含可染色盐的溶液引入具有亲水性内表面的微室中,以通过结合核酸来浓缩核酸 酸在微室的内表面上; 并通过向该室加入PCR混合物进行聚合酶链式反应(PCR)。 由于核酸可逆地结合到微室的内表面,与其中发生不可逆结合的氧化铝的表面相比,PCR产率更高。 此外,所有过程都在单个微室中顺序进行,以便可以减少样品数量,消耗品,时间和处理和分析的劳动力,可以提高检测灵敏度,并且样品交叉污染的风险在没有样品时显着降低 通过消除样品的运输而损失。 因此容易提供用于浓缩和扩增核酸的完整的自动化系统。

    • 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.
    • 提供了使用固定的水凝胶或聚乙二醇(PEG) - 水凝胶共聚物来分离和纯化核酸的方法。 该方法包括:将含官能团的水凝胶或PEG-水凝胶共聚物固定在基材上; 将含有盐和核酸的混合样品溶液加入到水凝胶或PEG-水凝胶共聚物固定的底物中,以将核酸与水凝胶或PEG-水凝胶共聚物结合; 洗涤核酸结合的水凝胶或PEG-水凝胶共聚物; 并使用洗脱溶剂从水凝胶或PEG-水凝胶共聚物中洗脱核酸。 因此,即使没有添加单独的化学物质也可以进行核酸的结合和洗脱,并且可以最小化对后续过程(例如PCR)的影响。 此外,可以根据PEG浓度调节结合核酸的量和强度,并且在基材上存在水凝胶化合物能够进行图案化。
