Biochip analyzer

Abstract

The invention provides a biochip analyzer. The biochip analyzer comprises a rack; a PCR amplification device, a chip feeding device and a sample detection device are arranged on the rack; the PCR amplification device comprises a first shell and a heating platform; the heating platform has a retraction position in which the heating platform is located in the first shell and an extension position in which the heating platform is located outside the first shell; and a to-be-detected sample placing area is formed at the top of the first shell. The biochip analyzer further comprises a transfer device; the transfer device can be used for transferring a sample on the heating platform at the extending position to the to-be-detected sample placing area, transferring the sample from the to-be-detected sample placing area to the sample detection device, and transferring a chip in the chip feeding device into the sample detection device. According to the biochip analyzer of the invention, the transfer device and a plurality of functional devices cooperatively act, so that the functions of PCR amplification, sample and biochip feeding, biochip detection and analysis and the like can be realized, the automation degree and the integration degree are high, the analysis and detection efficiency is higher, and the labor cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of digital PCR analyzers, in particular to a biological chip analyzer. Background technique [0002] Digital PCR is the latest quantitative technology. Nucleic acid quantification based on single-molecule PCR method is an absolute quantitative method. It mainly adopts the microfluidic or microdroplet method in the current hot research field of analytical chemistry to dilute a large amount of The final nucleic acid solution is dispersed into microreactors or microdroplets of the biochip, and the number of nucleic acid templates in each reactor is less than or equal to 1, so that after PCR cycles, a reactor with a nucleic acid molecule template will give Fluorescent signal, the reactor without template will have no fluorescent signal, according to the relative ratio and the volume of the reactor, the nucleic acid concentration of the original solution can be deduced. Traditional PCR analyzers have a single fu...
