Gold nanoparticles studied in an in vitro tool for drug screening against SARS-CoV-2

[ad_1] Scientists have measured the interaction of the spike protein (S) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with nano-gold colloids. These nanoparticles functionalized with protein S have different spectroscopic signals allowing new information on the protein to be extracted. The ongoing COVID-19 (2019 coronavirus disease) pandemic, caused …

A different strategy for SARS-CoV-2 wastewater detection

[ad_1] Researchers have tested a variety of RNA concentration and extraction methods and tests to develop a protocol for testing SARS-CoV-2 in wastewater, which may help improve COVID-19 surveillance. COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is typically monitored by diagnosing symptomatic patients and tracing their contacts. …
