These nanocomposites have been shown to exhibit antiviral activity in MDCK cells infected with H5N1 influenza A virus. The nanocomposites containing phosphorothioate oligonucleotides inhibited virus replication ~130-fold.

The antiviral activity of oligonucleotides of all three types, when delivered by Lipofectamine, has been significantly lower compared to the oligonucleotides delivered in the nanocomposites.
