Important nanoparticle characteristics for adjuvanticity. To be recognized and to stimulate innate immunity, metallic nanoparticles (MeNPs) must have some physicochemical traits that allow for interactions with host cells and lead to the generation of a response. APCs, antigen-presenting cells; MeNPs, metallic nanoparticles; Th, T-helper cell.
