Abstract: In accordance with one embodiment of the present invention, there is disclosed an apparatus for nucleic acid extraction and an operation method thereof. The apparatus for nucleic acid extraction includes: a first rack having a plurality of sample tube receivers arranged in a circle; a second rack having a plurality of elution tube receivers arranged in a circle on an outer side thereof and a washing solution receiver positioned at the center thereof, a part of the washing solution receiver extending outwards to have projections formed in alternation with a plurality of the elution tube receivers; a main body having the first and second racks arranged to position the first rack on the top of the second rack; a rotational driver for separately rotating the first and second racks; a dispenser for separately dispensing a washing solution and an eluting solution into sample tubes; and a pressurizer for maintaining the inside of the sample tubes under raised pressure.

Abstract: The present invention relates to an ultra-high speed real-time PCR device on the basis of a lab-on-a-chip for detecting bacteria that causes food poisoning pertaining to agricultural food and a food poisoning detection method using the same. The present invention can provide a micro PCR chip which can simultaneously accommodate a plurality of small-volume samples and concurrently secure maximum thermal contact efficiency with a heating block so as to secure rapid results, and accurately measure an optical signal emitted from a nucleic acid amplification product even without any separate filtering or processing. Further, on the basis of the PCR chip, the present invention can provide a real-time PCR device which can rapidly obtain a nucleic acid amplification result of which the reliability is secured even without a complicated light-signal measuring module.
