ABSTRACT
COVID – 19 is a contagious disease caused by severe acute respiratory syndrome (SARS-CoV2). The rate at which COVID – 19-virus spread from epidemic to pandemic within a short period is quite alarming. As of July 2020, the Dashboard of the World Health Organization (WHO) recorded over 15 million COVID – 19 cases across 213 countries, with mortality of over 620,000. The governments and healthcare agencies responsible for mitigating the virus's spread have adopted several strategies to end the pandemic. However, all hands were on deck to establish the standard treatment modalities of SARS-CoV-2 through inventing new drugs, vaccine candidates, or repurposing the existing medicines and robust diagnostic tools, in addition to other technological innovations. Therefore, nanotechnology’s employment would play a vital role in bringing multidisciplinary ways of developing affordable, reliable, and powerful tools for diagnosis, in addition to personal protection and effective medicines. Additionally, nanosensors' application would significantly aid the diagnoses of the COVID–19 even on asymptomatic patients, and thus would be an essential means for determining its prevalence. Likewise, nanoscale fibers can optimize personal equipment protection and allow their reusability for medical and economic benefits. Accordingly, the literature was intensively reviewed by searching for the combinations of the research keywords in the official scientific databases such as Science Direct, PubMed, and Google Scholar. Hence, this research highlighted the perspective contributions of nanotechnology in the war against the COVID-19 pandemic.

ABSTRACT
The World Health Organization (WHO) declared COVID -19 a pandemic on March 11 2020. As of today, there have been 122 million COVID -19-update cases worldwide, and the counting goes on. Unfortunately, strategic measures such as total lockdown, social and self-isolation, and gradual lifting of some of these restrictions both pose economic, social, and psychological distress and are thought to have affected people more than the virus itself. There is no specific antiviral drug available at this time. However, there are currently five main vaccines on the market that aim to protect the population from contracting the coronavirus. Moderna, Pfizer/BioNTech, Oxford/AstraZeneca, Sputnil V, and Sinopharm vaccines are among those included. Furthermore, developing an effective medication that is reliable for the treatment may be more effective, but it is more difficult. To accomplish this, molecular bio-interaction, virulence, clinical, and pathological features of COVID -19 viruses must be clearly understood. Additionally, the designation of potential antiviral drugs in the form of nanomedicines will optimize the therapeutic outcome and improve the quality of life. This study expanded on the clinical, pathological, and virulence features of COVID-19 and highlighted the need to investigate nanomedicines as a gold option that could potentiate the world to win the fight against COVID-19 infection.
