Natural Antimicrobial Materials

Antiviral polysaccharide and antiviral peptide delivering nanomaterials for prevention and treatment of SARS-CoV-2 caused COVID-19 and other viral diseases

“…[ [39] , [40] , [41] ]. Due to the promising characteristics of natural polymers/peptides such as biocompatibility, reproducibility, biodegradability, abundance, non-toxicity, and cleanness, many of them have been spotlighted for antiviral therapeutics [ 40 , [42] , [43] , [44] ]. Combining nanotechnology and natural polymer/peptide technology, the nanomaterials delivering natural bioactive constituents have demonstrated a superior protective/therapeutic performance to prevent, alleviate, or eradicate viral infections [ 42 ].…”

“…For instance, they are cationic and amphipathic, with the net charges of +2 and + 9 at the neutral pH range [ 51 , 52 ]. These characteristics are promising for their interaction with cell membrane, microbial surface, and internal structure [ 43 ]. Thus, a diverse range of microorganisms, especially fungi, bacteria, and viruses are effectively eliminated or prevented from proliferating [ 52 ].…”
