Help curb the spread of the new crown

Science and Technology Daily, Beijing, September 23 (Reporter Liu Xia) According to a report by the Physicist Organization Network on the 22nd, an international scientific research team composed of scientists from the United States, Argentina and Germany has developed a new type of sensor that integrates a specially designed sensor.

The latest research leader, Lu Yi from the University of Illinois, said: "Research on the new coronavirus has proved that the level of viral RNA has the smallest relationship with the virus

The test to detect infectious viruses is called a plaque test, but it requires special preparation and several days to get results

The researchers said that the ability to distinguish between infectious and non-infectious viruses, and detect a small amount of viruses that may contain other contaminants from unprocessed samples, is not only for rapid diagnosis of patients who are still infectious in the early stage of infection or after treatment Very important, and also very important for environmental monitoring

Lu Yi said: “This technology can be further expanded to detect other new spreading viral pathogens that have caused public concern, such as Norwalk virus and Enterovirus, or to detect new mutant strains of the new coronavirus

Researchers are working to further improve the sensitivity and selectivity of the sensor, and plan to use it in combination with other detection methods
