Novel Protein-Based Sensors Rapidly Detect Coronavirus Antibodies
Written by AZoSensorsJan 29 2021
A new method has been developed by researchers to detect the proteins that constitute the pandemic coronavirus, along with its antibodies. They created protein-based biosensors that glow on combining with components of the virus or particular COVID-19 antibodies.

This discovery could allow quicker and more extensive testing in the forthcoming days. The study has been published in the
Nature journal.
At present, a majority of the medical labs depend on a method known as RT-PCR for the diagnosis of coronavirus infection. The method involves amplifying genetic material from the virus so that it can be viewed and needs specialized equipment and staff. Moreover, it consumes laboratory supplies that are currently in high demand worldwide. Supply-chain shortages have decelerated COVID-19 tes

Scientists have created a new way to detect the proteins that make up the pandemic coronavirus, as well as antibodies against it. They designed protein-based biosensors that glow when mixed with components of the virus or specific COVID-19 antibodies. This breakthrough could enable faster and more widespread testing in the near future. The research appears in
Nature.
To diagnose coronavirus infection today, most medical laboratories rely on a technique called RT-PCR, which amplifies genetic material from the virus so that it can be seen. This technique requires specialized staff and equipment. It also consumes lab supplies that are now in high demand all over the world. Supply-chain shortfalls have slowed COVID
