“…COVID-19, a new disease caused by SARS-CoV-2, is a public concern, prevalent all over the world, and killing countless people [ [1] , [2] , [3] , [4] ]. To date, various systems including antimicrobial metallic, metal oxide nanoparticles, and other antiviral materials were employed to fight against microorganisms [ [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] ]. For example, Randriantsilefisoa et al [ 16 ] prepared hydrogel nanocomposites based on Au nanoparticles, sialic acid, polyethylene glycol, and polyglycerol cyclooctyne to catch the influenza virus.…”
