Comparison of the organic antiviral materials

Types	Performance	Mechanism of antiviral	References
N-halamine	Contact with 0.5% N-halamine for 30 min, the infection rate reduce seven orders of magnitude	Interrupt RNA specific sites	[63]
N,N-dodecyl methylpolyethylenimines (PEIs)	Kill the influenza virus with essentially 100% efficiency within minutes	Damage lipid membrane	[64]
Chitosan	At concentration of 1 g/L inhibited the infection of NCV	Stimulation of immune response	[66]
Zinc-tetra(4-N-methylpyridyl)porphine (ZnTMPyP4+)	After exposure to light for 60 min, inactivating bacterial and viruses at least 99.89% and 99.95%	Production of ROS	[71]
Sunlight active nanofiber membranes	Killing rate of bacteria and viruses higher than 99%	Production of ROS	[73]
