Hierarchical carbon materials with tuned porosity have shown effective adsorption of many cytokines, including IL-6 and even the largest ones, such as TNF-α.103 Based on their demonstrated outstanding performance in removing sepsis-associated pro-inflammatory cytokines from blood, mesoporous carbon adsorbents with hierarchical structure, tuned pore size, and surface chemistry, as well as graphene with open and accessible surfaces104 have significant potential to quickly remove inflammatory cytokines associated with CRS and to prevent mortality arising from an uncontrolled inflammatory cascade, thereby providing enough time for the defense mechanisms of the human body to fight the virus.
