Washington: Scientists from all over the world are engaged in defeating the coronavirus. Corona vaccination has also started in Britain, China, and Russia. The good news is that a paper test of Covid-19 has been developed under the leadership of Professor Dipanjan Pan, a scientist of Indian origin. This paper test will be equipped with a ‘paper-based electrochemical sensor’ which will detect the presence of coronavirus within five minutes. It is obvious that if this paper test is successful, then crores will benefit.
A report published in ACS Nano magazine
Researchers at the University of Illinois in the US have developed a ‘graphene-based electro biosensor’ with an ‘electrical read-out setup’ to detect the presence of genetic particles of SARS-COV-2. According to research published in the journal ‘ACS Nano’, this biosensor has two components – 1. measuring ‘electoral read-out’, 2. to detect the presence of viral RNA.
The researchers, led by Professor Dipanjan Pan, applied a layer of ‘graphene nanoplatelets’ to the filter paper to make a conductive film for its manufacture, and then they designed a predetermined top of graphene as a contact pad for electrical read-outs. With a gold electrode placed. Both gold and graphene have greater sensitivity and conductivity, which makes this platform ultrasonic to detect changes in electrical signals. The team of researchers hopes that apart from Covid-19, it can also be used to detect different diseases.
