[Explanation] In February 2020, the team of Professor Chen Chen from Guangxi Guilin University of Electronic Technology (hereinafter referred to as the research team) successfully developed a new type of coronavirus IgM/IgG antibody combined test strip. It only takes 3 to 5 minutes to complete the initial screening of the new coronavirus test. A few days ago, the reporter interviewed Zhao Feijun, a member of the research team, to understand the story behind the development of test strips.
[Explanation] Zhao Feijun introduced that in January of this year, Chen Chen, a professor at the School of Life and Environmental Sciences of Guilin University of Electronic Technology, learned of the news that the epidemic was getting worse. Paper) to conduct a tough experiment.

The principles of the two methods are basically the same, so we are on the basis of the original project, we have made improvements, and finally applied to the detection of this new coronavirus.
[Explanation] After the efforts of the research team, the new coronavirus test paper was successfully developed on February 12. Subsequently, with the support of all sectors of society, the test paper was formally put into use after clinical confirmation.
[Explanation] Zhao Feijun said that fingertip blood is used as the type of test sample due to the convenience of collection. After collecting the sample, drop the fingertip blood and diluent into the test hole, and the result will be obtained after 3 to 5 minutes. This method enables rapid diagnosis of suspected new crown patients and on-site screening of close contacts, reducing the risk of exposure of medical staff during the collection of nucleic acid samples.

First of all, the first line is the C line, which is the test line, that is, if the test is successful, this line will be generated. When either line of the G line and M line is generated, it means that the person has the new coronavirus . So if there is a patient who has the new crown virus, or has had the new crown virus, our product will show positive. When our product has a positive result, we are instructing him to go to the hospital for another nucleic acid test.
[Explanation] In June of this year, relevant departments in Beijing detected the new coronavirus from the cutting boards of imported salmon during random inspections in the Xinfadi market. Professor Chen Cheng's scientific research team has a new research goal. They hope to "upgrade" the test paper again, so that the test paper can quickly detect the presence of the new coronavirus in the air and food.
[Explanation] It is understood that the "upgraded version" of the test paper has been successfully developed and will be put into the market after verification and approval.
[Concurrent] (Zhao Feijun, member of the biological research team of Guangxi Guilin University of Electronic Technology)
We hope that by doing another antigen test, a quick test can be carried out, such as in the air or in food, in three to five minutes, or five to ten minutes, and a result can be obtained quickly.
