    摘要: The present invention relates to a method of enriching a pathogen using an homobifunctional imidoester group, and the method of enriching a pathogen and extracting nucleic acids using homobifunctional imidoester compound (DMA, DMP, DMS) according to the present invention can quickly extract a small amount of pathogen contained in a sample without the use of special equipment and can be used as in situ diagnosis, and since it is possible to enrich a pathogen and extract nucleic acids simultaneously in one tube or a chip, it has the advantage of being more efficient than the conventional method, saving time and cost, and being easy to use.

    摘要: The present invention relates to a method for lysing pathogen lysis and a method for extracting nucleic acid using zinc oxide nanostar, and the method for extracting nucleic acid using zinc oxide nanostar according to the present invention can extract nucleic acids by lysing cells of a pathogen without using a lysis buffer and can extract nucleic acid of high-purity and high-concentration by preventing nucleic acid degradation and fragmentation through various substances including salts contained in the lysis buffer at high concentration. In addition, the zinc oxide nanostar of the present invention (200 to 900 nm) has superior cell lysis capacity compared to the conventional zinc oxide nanoparticles (20 to 50 nm), thereby increasing the nucleic acid extraction efficiency and can extract at room temperature without a heating step to use as a field diagnostic method.

    摘要: The present invention relates to a ribonucleic acid (RNA) extraction method using a solid subject, the method including activating a subject with a reactive amine group, injecting a sample having 1×101 to 1×103 cells/ml and a dimethyl suberimidate (DMS) compound or a dimethyl pimelimidate (DMP) compound into the subject, and forming a complex having the RNA within the sample and the compound, and extracting the RNA by treating elution buffer to the subject on which the complex is formed. The subject, particularly, the thin film device used for extracting the RNA, has improved hydrophilicity compared to the conventional silicon substrate, so that RNA is extracted more efficiently.
