Device can detect anti-virus antibody in 20 minutes


Researchers have succeeded in detecting anti-avian influenza virus antibody in blood serum within 20 minutes, using a portable analyzer they have developed to conduct rapid on-site bio tests. If a suitable reagent is developed, this technology could be used to detect antibodies against SARS-CoV-2, the causative virus of COVID-19.

Rolling into the deep


Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment.

COVID-19 tests compared


In an important, comprehensive, and timely review, an team from the University of California Berkeley details the methodologies used in nucleic acid-based tests for detecting the presence of SARS-CoV-2, the virus that causes COVID-19. They show that these tests vary widely in applicability to mass screening and urge further improvements in testing technologies to increase speed and availability.
