Abstract: In some embodiments, the present invention provides methods of treating oxidative stress in a subject by administering a therapeutic composition to the subject. In some embodiments, the therapeutic composition comprises a carbon nanomaterial with anti-oxidant activity. In some embodiments, the anti-oxidant activity of the carbon nanomaterial corresponds to ORAC values between about 200 to about 15,000. In some embodiments, the administered carbon nanomaterials include at least one of single-walled nanotubes, double-walled nanotubes, triple-walled nanotubes, multi-walled nanotubes, ultra-short nanotubes, graphene, graphene nanoribbons, graphite, graphite oxide nanoribbons, carbon black, oxidized carbon black, hydrophilic carbon clusters, and combinations thereof. In some embodiments, the carbon nanomaterial is an ultra-short single-walled nanotube that is functionalized with a plurality of solubilizing groups.

Abstract: In some embodiments, the present disclosure pertains to methods of treating an inflammatory disease in a subject by administering a carbon material to the subject. In some embodiments, the carbon material selectively targets T cells in the subject. In some embodiments, the carbon material includes poly(ethylene glycol)-functionalized hydrophilic carbon clusters. In some embodiments, the administration of the carbon material to the subject reduces or inhibits T cell-mediated reactions in the subject. In some embodiments, the carbon material selectively targets T cells over other types of immune cells by preferential uptake into the T cells. In some embodiments, the carbon material reduces or inhibits proliferation of targeted T cells, reduces or inhibits cytokine production by targeted T cells, and reduces intracellular oxidant content in targeted T cells. In some embodiments, the present disclosure pertains to methods of modulating T cells ex-vivo by incubating the T cells with a carbon material.
