Recent Advances on Nanotechnology-Based Strategies for Prevention, Diagnosis, and Treatment of Coronavirus Infections

摘要

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is exponentially spreading across the world, leading to an outbreak of serious viral pneumonia. Antiviral therapies using chloroquine, hydroxychloroquine, and favipiravir have been approved by several countries to increase the quality of life of SARS-CoV-2-infected patients. Currently, several companies are intensively working on the production of coronavirus (CoV) vaccines, resulting in some specific vaccines that have been approved for CoV infections in humans. Nevertheless, efficient and specific prevention, treatment, and diagnosis are urgently required to combat the biological diversity and rapid mutation in CoV infections. Recently, significant attention has devoted to nanoformulation or nanoparticles (NPs) due to their specific features like high surface-to-volume ratio, drug encapsulation abilities, and specific optical properties to remove the complications of applied conventional therapeutic and diagnosis options. In this regard, NPs are increasingly used as new anti-CoV agents, vaccine carriers or adjuvants, and nanoscale biorecognition elements. The present review article provides a comprehensive discussion on the recent updates regarding the prevention, diagnosis, and treatment of different CoV infections with an emphasis on the application of NPs in vaccination, treatment, and diagnosis of CoV infections.
