Rapid Covid-19 Test uses nanoparticle technique
Scientists from the University of Maryland School of Medicine (UMSOM), USA, have developed an experimental diagnostic test for Covid-19 that can visually detect the presence of the virus in 10 minutes.
It uses an 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 for analysis.
The authors published their work in the American Chemical Society’s nanotechnology journal ACS Nano.
The team believe the test may detect RNA from the virus as early as the first day of infection.
