The RNA sensor MDA5 detects SARS-CoV-2 infection | bioRxiv

27/03/2021· Human cells respond to infection by SARS-CoV-2, the virus that causes COVID-19, by producing cytokines including type I and III interferons (IFNs) and proinflammatory factors such as IL6 and TNF. IFNs can limit SARS-CoV-2 replication but cytokine imbalance contributes to severe COVID-19. We studied how cells detect SARS-CoV-2 infection.

A new biosensor for the COVID-19 virus

The new focus: a sensor that can quickly and reliably detect SARS-CoV-2 - the new coronavirus. But the idea is not quite so far removed from the group's previous research work: even before the COVID-19 began to spread, first in China and then around the world, Wang and his colleagues were researching sensors that could detect bacteria and viruses in the air. As early as January, the idea of using this …

Optical biosensor detects SARS-Cov-2: Sensor measures virus ...

23/04/2020· The sensor combines two different effects to detect the virus safely and reliably: an optical and a thermal one. The sensor is based on tiny structures of gold, so-called gold nanoislands, on a glass substrate. Artificially produced DNA sequences that match certain RNA sequences of the SARS-CoV-2 virus are applied to the nanoislands. The new ...

An electrochemical SARS-CoV-2 biosensor inspired by glucose …

SARS-CoV-1 is not present in the community and is therefore unlikely to impact the performance of this sensor. HCoV-NL63 primarily affects paediatric patient groups, which could limit the sensor to adult diagnostics if signal stratification is not possible. The current time to result based on the presented results is 30 min, which is competitive with existing SARS-CoV-2 assays but significant scope exists to …
