Covid-19: Novel Coronavirus Outbreak

An electrochemical biosensor was constructed by convectively assembling polystyrene (PS) beads on a gold electrode to detect SAR-Cov-2 virus via partial nanochannel blockage by virus particles. Nanochannel blockage hinders the diffusion of a redox probe and causes attenuation of oxidation current, allowing quantification of the viral load by measuring the changes in oxidation currents before and after virus incubation.

High flow nasal cannula (HFNC) reduces the need for intubation in patients with hypoxaemic acute respiratory failure (ARF). Our data suggest that a trial of HFNC could be considered to increase chances of survival in patients with ARF due to coronavirus disease 2019 (COVID-19) pneumonitis and a do-not-intubate (DNI) order, especially in those with a good WHO performance status.

Synthetic SARS-CoV-2 and Omicron variant detection with a cost-effective silicon nanowire sensor has been demonstrated with high sensitivity, selectivity, and a fast response. The sensor reaches a 4 cps limit of detection (LoD), even for the Omicron variant, without any genome amplification, and with strong selectivity. The platform is made with industrially compatible techniques, which in perspective may allow a widespread diffusion.
