Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of biological molecule detection, especially to a sequencing analysis integrated device. BACKGROUND
[0002] Nanopore sequencing technology is the third generation sequencing technology, which uses nanopore as a biosensor to identify and measure the sequence of single DNA and RNA molecules. The working principle is that the DNA or RNA molecule passes through the nanopore under the control of the motor protein. Since the current changes caused by different bases passing through the nanopore are different, different bases are determined by monitoring the current signal to achieve sequencing. Compared with previous sequencing technologies, nanopore sequencing can provide long read sequencing, and can monitor the sequencing results in real time according to the current change when a single molecule passes through the pore.
[0003] Before nanopore sequencing, nucleic acid extraction, sequencing library construction and other pretreatment processes are needed. Sequencing library construction refers to a series of processes performed on the original DNA or RNA sample before next-generation sequencing to convert it into a format suitable for sequencing instrument reading. The process usually includes fragmentation, end repair, adapter addition, PCR (Polymerase Chain Reaction) amplification and other steps. In traditional technology, the above-mentioned nucleic acid extraction and sequencing library construction and other experimental steps are complex and time-consuming, and require high standardization of experimental personnel operation. And the current nanopore sequencing pretreatment, sequencing and sequencing result analysis three workflows are relatively independent and separated. In order to realize instant sequencing at the border port or other non-laboratory scenes, rapid detection of pathogens and other pathogens is needed, and a full-process integrated and portable sequencing device is needed.
[0004] There are instruments in the prior art only for sequencing pretreatment, which can be better applied to nanopore sequencing technology to replace manual operation and simplify the operation process. On the other hand, for example, the Chinese invention patent with publication number CN115948235A discloses a "DNA sequencing analysis integrated device based on solid-state nanopore", which integrates nanopore sequencing acquisition technology, membrane clamp control technology, software control technology, 5G communication processing unit and operation display terminal into the same device, which can complete the complete process of DNA nanopore sequencing operation, including pore event recognition, single and double strand detection, acquisition of electrical signals, data file packaging, transmission and reception of data analysis, and DNA sequencing sequence. The device realizes the acquisition, transmission and analysis of data obtained by sampling and sequencing in the field by a portable "terminal" device. However, the device only solves the problem of relative independence of current sequencing and sequencing result analysis, and the nanopore sequencing pretreatment process still relies on the existing independent processing method, which needs to be further improved.
