New York, May 30 -- A team of US scientists led by an Indian-origin researcher has developed an experimental diagnostic test for COVID-19 that can visually detect the presence of coronavirus in 10 minutes.
Scientists from the University of Maryland School of Medicine developed the test that uses a simple assay containing plasmonic gold nanoparticles to detect a colour change when the virus is present.
The test does not require the use of any advanced laboratory techniques, such as those commonly used to amplify DNA, for analysis.
"Based on our preliminary results, we believe this promising new test may detect RNA material from the virus as early as the first day of infection. Additional studies are needed, however, to confirm whether thi...
