Applications of nanomaterials in COVID-19 pandemic

The novel coronavirus 2019(COVID-19)pandemic represents one of the biggest global health threats in the last two decades,so researchers around the world are searching for solutions and treatments for COVID-19.At the time of writing,there are no specific drugs that have demonstrated suitable effectiveness in treating COVID-19.The current challenge involves designing tools for the prevention,rapid and accurate diagnosis,drug delivery,and effective treatment of this novel coronavirus.In this short review,we discuss how nanotechnology offers new ways to combat COVID-19,and how nanomaterials can be applied to control the COVID-19 outbreak.We also summarize relevant studies regarding the use of nanomaterials for preventing viral spread,preparing vaccines,and diagnosing coronavirus,as well as studies that show how nanoparticles can be used as drug delivery systems for the treatment of viral infections.Research on nanotechnology-based diagnosis,drug delivery,and antiviral therapy is currently in the early stages.However,the unique chemical properties of some nanomaterials highlight the broad prospect of nanomaterials in the future,and we propose that they will play an important role in the fight against COVID-19.
