    The integrated self-service nucleic acid detection cartridge needs to first collect the pharynx swab or nasopharyngeal swab, feed into the integrated cartridge for reaction, and finally directly read the colloidal gold test paper resultsThe kit is designed with two putters, the user sends the sample into the kit, pushes the two putters up and down one, and can view the results in 30 minutesBai Netwei, a researcher at Tsinghua University's School of Pharmacy at, said the research team used nest-type temperature amplification (ITA) technology for nucleic acid testingHe explained that nucleic acid detection commonly used detection methods, such as fluorescence PCR (Polymerase Chain Reaction, polymerase chain reaction), often need to be in a harsh experimental environment and professional equipment, after 2-3 hours of tedious operation and reaction to get the test resultsIn addition, the sampling process is very vulnerable to impurities, resulting in the loss of nucleic acid extraction, which often leads to "false negative" conditionsDuring the design process, the research team reduced the complexity of the detection process and reduced the number of "false negative" cases caused by impurities by optimizing the cleavage process and back-end amplification reagents, said Li Weiqing, a researcher at Tsinghua University's School of Pharmacy,Li said that 19 samples of QPCR (traditional real-time fluorescence quantitative PCR) positive patient samples were reviewed using newly developed technology, and the results showed that all samples of the 19 positive patients could be detected, it is learned that the next step, the project team will promote small batch cartridge assembly, verify the feasibility of batch production, while working with hospitals to speed up the validation of clinical samples.
