The test uses a simple assay containing gold nanoparticles to detect a colour change when the virus is present WASHINGTON : Scientists have developed an experimental diagnostic test for COVID-19 that can visually detect the presence of the novel coronavirus in 10 minutes, an advance that may lead expansion of testing for the virus across the world.
According to the study, published in the journal ACS Nano, the test uses a simple assay containing gold nanoparticles to detect a colour change when the virus is present.
The researchers from the University of Maryland School of Medicine (UMSOM) said the test does not require the use of any advanced laboratory techniques, such as those commonly used to make multiple copies of the viral genetic
