Former AU student and young scientist develops biosensor that can detect Covid from sweat

Biosensors would be a one-step identification or sensing technique

Biosensors can lead to a new age of effective, cheaper testing kits capable of detecting COVID-19 instead of nasal or throat swabs

A former student of Allahabad University (AU), Amit Dubey, claims to have developed a biosensor that can detect COVID-19 infection through sweat samples. Dubey, 34, is working as a senior scientist at Quanta Calculus, Greater Noida.

Dubey claims that he has developed the world’s first specific, reliable ultra-small gold nanoclusters for biomedical and biosensing applications to detect Covid.

Sharing his research, findings of which have been recently published in ‘Luminescence: The Journal of Biological and Chemical Luminescence‘, a US journal published by Wiley, Dubey said the biosensors would be a one-step identification or sensing technique.

His work can lead to a new age of effective and cheaper testing kits capable of detecting Covid-19 using just the sweat of an individual instead of nasal or throat swabs that kits of today need.

Ultra-small gold nanoclusters, with diameters less than 2 nm, are attracting increasing attention due to their unique size-dependent physiochemical properties which include strong luminescence and excellent biocompatibility.

“I hope this research can lead to a new generation of low-cost biosensors,” the scientist said.
