OCT 06, 2020 SEOUL: Scientists have developed a new method that allows anyone to easily and quickly detect COVID-19 in just 30 minutes, and is as accurate as the current PCR diagnostic test. The SENSR technology developed by researchers at Pohang University of Science & Technology (POSTECH) in South Korea diagnosis COVID-19 based on the RNA sequence of the virus, reducing the stress on one single testing location and avoiding contact with infected patients as much as possible. RNA is a nucleic acid that mediates genetic information or is involved in controlling the expression of genes. The biggest benefit is that a diagnostic kit can be developed within a week even if a new infectious disease appears other than COVID-19, according to the research published in the journal Nature Biomedical Engineering. The researchers noted that PCR molecular test currently used for COVID-19 diagnosis has very high accuracy but entails a complex preparation process to extract or refine the virus. The test is not suitable for use in small farming or fishing villages, or airport or drive-thru screening clinics as it requires expensive equipment as well as skilled experts, they said. The researchers designed the test kit to produce nucleic acid binding reaction to show fluorescence only when COVID-19 RNA is present. The virus can be detected immediately...
