TNF and cancer: In a recent study, an anti‐inflammatory and tumor‐targeted photothermal nanoagent (pDA@aspirin@CM) was presented, by combining PDA nanospheres, anti‐inflammatory drug acetylsalicylic acid (aspirin), and cancer cell membrane coating.108 In this design, pDA nanospheres could effectively kill cancer cells via NIR laser mediated photothermal effect, aspirin could suppress PTT‐induced inflammation response via down‐regulation the levels of inflammatory cytokines (e.g., IL‐6 and TNF‐α), and the 4T1 cancer cell membrane coating could provide homologous tumor targeting, respectively.
