    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: Provided is a lysis method for cells or viruses, including: immobilizing a metal-ligand complex on a solid support; and mixing the complex immobilized on the support with a cell or virus solution. According to the lysis method, by immobilizing a chemical on a solid support to perform cell lysis, the dilution problem according to the addition of a cell lysis solution can be resolved and a separate process of removing the chemical is not required so as to reduce the steps upon LOC implementation. In addition, since a variety of solid supports, such as chips, beads, nanoparticles etc. can be used, cell lysis apparatuses of various forms can be fabricated.
