“…The nanoparticle delivery systems enable constant systemic flow and maintained the liberation of antiviral molecules, therefore maximizing their therapeutic actions [ 38 , 43 ]. Different types of NPs have been employed in the development of nanoscale delivery systems and characteristics of these nanoparticles can be changed by regulating the size of the system, conjugating needed groups to the surface and controlling its surface charges [ 38 ]. A broad range of NPs, including lipid nanoparticles, AuNPs, polymeric NPs and AgNPs are often used as carriers for embedded antiviral molecules [ 38 , 44 , 45 ].…”
