So what he effectively did is create chitosan nanoparticles loaded with protein/carbon nanoparticles. This, I would imagine, is to allow the proteins to help bypass every protease, lysosome, and other defensive mechanisms that your body and cells have to protect against non-self proteins. These antigens, would then need to be presented by major histocompatability complexes to induce an immune response.
