Research labs that measure and analyze airborne pollutants have a new focus — to develop a sensor that can quickly and reliably detect the SARS-CoV-2 virus.
Most laboratories use a molecular method to detect viruses that can lead to respiratory infections. This method, called reverse transcription polymerase chain reaction (RT-PCR), can detect viruses in tiny amounts, but can be time-consuming and prone to error.
The team of professor Jing Wang, who leads the Air Quality and Particle Technology group at ETH Zurich and a group at the Swiss Federal Laboratories for Materials Science and Technology (Empa), has developed an alternative test method — an optical biosensor that uses thermal effects to detect the virus…READ MORE
