Researchers from the Georgia State and Emory Universities have developed an “intranasal influenza vaccine” which utilizes graphene oxide for potent immunoenhancing effects. In other words, graphene oxide was found to improve the immune system when added to the vaccine.
The graphene oxide nanoparticles have extraordinary attributes for drug delivery or vaccine development, such as the ultra-large surface area for high-density antigen loading, and the vaccine showed superior immunoenhancing properties in vitro and in vivo. The nanoplatform could be easily adapted for constructing mucosal vaccines for different respiratory pathogens.Chunhong Dong, lead author of the study.
