The pandemic outbreak of SARS-CoV-2, with millions of infected
patients worldwide, has severely challenged all aspects of public
health. In this regard, early and rapid detection of infected cases
and providing effective therapeutics against the virus are in urgent
demand. Along with conventional clinical protocols, nanomaterial-based
diagnostics and therapeutics hold a great potential against coronavirus
disease 2019 (COVID-19). Indeed, nanoparticles with their outstanding
characteristics would render additional advantages to the current
approaches for rapid and accurate diagnosis and also developing prophylactic
vaccines or antiviral therapeutics. In this review, besides presenting
an overview of the coronaviruses and SARS-CoV-2, we discuss the introduced
nanomaterial-based detection assays and devices and also antiviral
formulations and vaccines for coronaviruses.
