Researchers at the University of Bristol have developed a machine to test how long Sars-CoV-2 can survive in tiny airborne particles

A nozzle releases a precise number of aerosol particles which levitate between two electric rings

The rings hold the particles suspended in place for as long as the test requires

Temperature, humidity and light can all be adjusted within the chamber

After minutes, hours or days the sample is extracted for study

and transferred to a dish of cells to see if the virus can infect and kill them
