Population-scale and rapid testing for SARS-CoV-2 continues to be a priority for several parts of the world. We revisit the in vitro technology platforms for COVID-19 testing and diagnostics—molecular tests and rapid antigen tests, serology or antibody tests, and tests for the management of COVID-19 patients. Within each category of tests, we review the commercialized testing platforms, their analyzing systems, specimen collection protocols, testing methodologies, supply chain logistics, and rel...

As a result of the multicomponent condensation reaction between the thiophenyli？dene？malo？no？nitril and malononitriles with (S)-(–)-1-phenylethylamine new heterocyclic dihydropyridine derivative [(S)-(–)-6-amino-2-imino-1-(1-phenylethyl)-4-(thiophen-2-yl)-1,2-dihydropyridine-3,5-dicarbonitrile] was synthesized. DMSO-d6 solutions of the new compound have been investigated in the presence of β-cyclodextrin by using the 2D DOSY method. As confirmed by our investigations, water molecules formed the ...
