Polyanine and its composites as sorbents of influenza viruses

Polyaniline and its composites with carbon nanotubes or silver nanoparticles are prepared and characterized via electron microscopy, spectroscopy, conductometry, and BET analysis. The in vitro and in vivo toxicities of the materials are studied, and then the materials are used as sorbents of the influenza A and B viruses. It is shown that the best sorption capacity with respect to all of the virus strains is exhibited by the polyaniline composite with silver, which provides for almost complete removal of viruses from aqueous solutions.
