A Novel Sensor for Rapid Detection of Respiratory Viruses

Viral respiratory diseases are easily transmissible and can spread rapidly across the globe, causing significant damage. The ongoing covid-19 pandemic is a testament to this. In the past too, other viruses have caused massive respiratory disease outbreaks: for example, a subtype of the influenza virus, the type A H1N1 virus, was responsible for the Spanish flu and the Swine flu outbreaks.
