Abstract: The present invention relates to an isothermal nucleic acid amplification technique based on a three-way junction structure that is formed as a ThIsAmp template; a ThIsAmp primer; and a nucleic acid are associated with each other through a hybridization reaction. Beyond the limitation of the conventional EXPAR technique, that is, the restricted application range that the EXPAR can be used only for detecting short target nucleic acids having a 3′-OH end, the method according to the present invention can detect target nucleic acids at excellent efficiency without being limited to kinds of target nucleic acids.

Abstract: The present invention relates to a detection method for detecting a target RNA contained in a sample with high sensitivity by using nicking/extension chain reaction system-based isothermal nucleic acid amplification (NESBA) that uses activity of a cleavage enzyme and a DNA polymerase. The NESBA of the present invention is a new concept isothermal target RNA detection method that realizes higher amplification efficiency than the existing NASBA technology and is deemed to be utilizable as a new concept diagnosis technology that can replace conventional target RNA detection technologies.

Abstract: The present invention relates to a target nucleic acid-detecting method using hairpin probe-assisted isothermal probe amplification (HIPAmp). According to the present invention, the method has the advantage of being able to conduct detection with respect to general-use target nucleic acids by solving the problem with the conventional isothermal nucleic acid amplification technique EXPAR with regard to limited uses of target nucleic acids.

Abstract: The present invention relates to a method of preparing nucleic acid-inorganic hybrid nanoflowers, which comprises allowing a nucleic acid to react with a solution of a metal ion-containing compound at room temperature, thereby forming a complex between the metal ion and the nitrogen atom of an amide bond or amine group present in the nucleic acid. According to the present invention, organic-inorganic hybrid nanoflower structures may be synthesized using nucleic acid in a simple manner under an environmentally friendly condition without any toxic chemical substance. The produced organic-inorganic hybrid nanoflower structures show a high DNA encapsulation yield, have resistance against nuclease, and show significantly increased peroxidase activity. Thus, these nanoflower structures may be widely used as a gene therapy carrier and in biosensing technology.
