Photo‐responsive carbon dots for pyroptosis‐mediated anti‐tumor application

open access: yesResponsive Materials, EarlyView.
Photo‐responsive CDs generate ROS to induce tumor cell pyroptosis, thereby stimulating antitumor immunity. Abstract Pyroptosis refers to a kind of lytic programmed cell death, characterized by the release of pro‐inflammatory cytokines during the process. Owing to its immune response stimulation ability, pyroptosis has garnered considerable attention in
