Nucleic acid detector

Abstract

The invention discloses a nucleic acid detector which comprises a base, a chip mounting assembly, a heating device, an optical detection device and a mechanical arm assembly; the chip mounting assembly is arranged on the left side part of the base and comprises a box body, a chip groove for accommodating a micro-fluidic chip is formed in the box body, and the chip groove is provided with a groove opening facing upwards; the heating device is arranged on the front side or the rear side of the chip mounting assembly; the optical detection device is arranged below the chip mounting assembly and is provided with an emitted light emitting part and an exciting light receiving part which are used for facing the lower end part of the micro-fluidic chip; the lower end part of the box body is provided with a hollow part capable of allowing emitted light to enter the chip groove and allowing exciting light to be emitted out of the chip groove; and the mechanical arm assembly comprises a mechanical arm capable of moving in the left-right direction, the mechanical arm is provided with a fork-shaped piece, and the fork-shaped piece is provided with a joint groove allowing the end of a piston of the micro-fluidic chip to be clamped in. The nucleic acid detector is compact in structure and small in size.

Description

technical field [0001] The invention belongs to the technical field of nucleic acid detection and relates to a nucleic acid detection instrument. Background technique [0002] Nucleic acid amplification detection technology is to provide in vitro amplification conditions for nucleic acid fragments to make them exponentially amplify in large quantities and add fluorescent dyes or fluorescent markers during the nucleic acid amplification process, and use optical devices to detect the strength of fluorescent signals. The process of obtaining nucleic acid amplification results through the analysis of fluorescent signals. During the nucleic acid amplification reaction, the reaction system needs to be heated. In addition, the nucleic acid detector can integrate nucleic acid amplification and detection. When the detection chip (usually a microfluidic chip) is placed in the nucleic acid detector, the reaction chamber of the detection chip (usually an amplification reaction chamber)...
