Covid-19 pandemic continues to spread across the world, the researchers from various laboratories have been coming up with the different strategies that can help to track the virus.The new study shows the possibility of detecting the virus through a rapid method with the use of a graphene biosensor which is adaptable to other viruses.A team led by professor Dipanjan Pan reported their findings in ACS Nano which shows that a bioengineering graduate student, Maha Alafeef from the University of Illinois Grainger has co-developed a rapid, ultrasensitive test using a paper-based electrochemical sensor that can detect the presence of the virus in less than five minutes."Currently, we are experiencing a once-in-a-century life-changing event.
