A new sensor detects corona viruses in the air | Der Bund

“The new Sars-CoV-2 coronavirus is transmitted by droplets, possibly even tiny floating droplets, as some studies suggest that have been published on the subject in recent weeks. These so-called aerosols stay in the air longer than larger droplets that are released when coughing or sneezing and which therefore also quickly fall to the ground. The new corona virus may even be transmitted when you speak.

An announcement by the Swiss Federal Institute for Materials Science and Technology Empa hence is timely. A team of researchers led by nanotechnologist Jim Wang has developed an optical biosensor that can determine the concentration of the new corona virus in the air. In the future, such a sensor could be used where many people move, for example in large train stations or in hospitals.”
