Fast SARS-CoV-2 virus detection using disposable cartridge ...

· Detection of the SARS-CoV-2 spike protein and inactivated virus was achieved using disposable and biofunctionalized functional strips, which can be connected externally to a reusable printed circuit board for signal amplification with an embedded metal–oxide–semiconductor field-effect transistor (MOSFET). A series of chemical reactions was performed to immobilize both a monoclonal …

Detection of Coronaviruses Using RNA Toehold Switch Sensors

· Meanwhile, sensors for SARS-CoV-2 were directly reacted with transcripts of the RT-LAMP amplicon yielded from 200 aM (sensor S1) or 1 fM (sensor S2) of initial target RNA in the cell-free reaction. To obtain the fold change, we first subtracted background absorbance that does not contain sensor DNA and trigger RNA from each absorbance value of the cell-free reaction with or without …

The RNA sensor MDA5 detects SARS-CoV-2 infection

· 75 MDA5 was an important cytosolic sensor for SARS-CoV-2 in these cells. The MDA5-MAVS-IRF3 76 signalling axis was necessary for production of type I and III IFNs, but not pro-inflammatory 77 cytokines, in response to SARS-CoV-2 infection. We further show that expression of the ISG 78 MxA is mainly induced in bystander non-infected cells in this system. made available under …

Proof of concept for real-time detection of SARS CoV-2 ...

· Rapid diagnosis is key to curtailing the Covid-19 pandemic. One path to such rapid diagnosis may rely on identifying volatile organic compounds (VOCs) emitted by the infected body, or in other words, identifying the smell of the infection. Consistent with this rationale, dogs can use their nose to identify Covid-19 patients. Given the scale of the pandemic, however, animal deployment is a ...

Development of a portable MIP-based electrochemical sensor ...

Herein, we report for the first time on the development of a MIP-based electrochemical sensor for detection of SARS-CoV-2 nucleoprotein (ncovNP). A key element of the sensor is a disposable sensor chip - thin film electrode - interfaced with a MIP-endowed selectivity for ncovNP and connected with a portable potentiostat. The resulting ncovNP sensor showed a linear response to ncovNP in the ...

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

· 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.
