Researchers have developed an assay that can detect the presence of SARS-CoV-2 in a nasal swab using a device attached to an ordinary smartphone, they report in the journal Cell. Although more research is needed before such a test can be rolled out, the results are promising and ultimately may be applicable to screening more broadly for other viruses. “Our study shows that we can do the detection part of this assay very quickly, making the measurement with mass-produced consumer electronics,” says Daniel Fletcher, a bioengineer at the University of California in Berkeley and co-senior author on the paper. “We don’t need fancy laboratory equipment.”
