Nanozymes have shown significant potential in cancer catalytic therapy by strategically catalyzing tumor-associated substances and metabolites into toxic reactive oxygen species (ROS) situ, thereby inducing oxidative stress promoting cell death. However, within the complex tumor microenvironment (TME), rational design of nanozymes factors like activity, reaction substrates, TME itself significantly influence efficiency ROS generation. To address these limitations, recent research has focused on exploring that affect activity developing nanozyme-based cascade systems, which can trigger two or more processes tumors, producing therapeutic achieving efficient stable with minimal side effects. This area remarkable progress. Perspective provides a comprehensive overview nanozymes, covering their classification fundamentals. The regulation nanozyme strategies are discussed detail. Furthermore, representative paradigms for successful construction systems treatment summarized focus revealing underlying mechanisms. Finally, we current challenges future prospects development biomedical applications.

Gasdermin (GSDM)-mediated pyroptosis involves the induction of mitochondrial damage and subsequent release DNA (mtDNA), which is anticipated to activate cGAS-STING pathway, thereby augmenting antitumor immune response. However, challenges lie in effectively triggering cancer cells subsequently enhancing activation with specificity. Herein, we developed intelligent self-cascaded pyroptosis-STING initiators cobalt fluoride (CoF2) nanocatalysts for catalytic metalloimmunotherapy. CoF2 a semiconductor structure enzyme-like activity generated substantial amount reactive oxygen species (ROS) under stimulation by endogenous H2O2 exogenous ultrasound. Importantly, discovered that Co-based nanomaterials themselves induce cells. Therefore, initially acted as inducers, caspase-1/GSDMD-dependent via Co2+ ROS, leading mtDNA release. Subsequently, were further utilized STING agonists specifically capable detecting pathway. These cascade events triggered robust response, modulating immunosuppressive tumor microenvironment into an immune-supportive state, providing favorable support therapy. This innovative strategy not only significantly impeded growth primary but also elicited response augment efficacy checkpoint inhibitors preventing distant progression. Overall, this study proposed self-cascade activating amplifying pathway specificity mediated pyroptosis, representing valuable avenue future
