Rapid COVID-19 tests are on the rise to deliver results faster to more people, and scientists need an easy, foolproof way to know that these tests work correctly and the results can be trusted. Nanoparticles that pass detection as the novel coronavirus could be just the ticket. Such coronavirus-like nanoparticles, developed by nanoengineers at the University of California San Diego, would serve as something called a positive control for COVID-19 tests.
Moderate temperature increases broke down SARS-CoV-2 virus-like particles structure on glass surfaces, suggesting that virus particles on surfaces will remain infectious longer. The findings agree with observations of other coronaviruses that appear to infect more people during the winter.
To address PPE shortages during the pandemic, scientists at Berkeley Lab and UC Berkeley are developing a rechargeable, reusable, anti-COVID N95 mask and a 3D-printable silicon-cast mask mold.
