Abstract Radiotherapy‐induced ferroptosis is accompanied by an adaptive response to the expression of tumor cell suppressor genes. Herein, a degradable and in situ generated silicomanganese composite system loaded with carbonic anhydrase (CA IX) inhibitor (4‐(2‐aminoethyl) benzenesulfonamide (ABS) constructed form DSiMn‐ABS nanosystem improve sensitivity hypoxic cells radiotherapy effect. The can be continuously degraded environment X‐rays, releasing Manganese dioxid (MnO 2 )and ABS; Thereby inhibiting activity CA IX, inducing acidification inside cells, regulating AMP‐activating protein kinase (AMPK)/Acetyl‐CoA carboxylase(ACC) axis increase ferroptosis, depleting glutathione (GSH) through MnO influencing peroxidase 4 (GPX4) activity, which further inhibits defense ultimately effectively improves therapeutic efficiency radiotherapy. Ultimately, inhibit growth. Therefore, this utilize double‐sensitized provide new ideas for

The demand for food has increased dramatically as the global population increases, putting more strain on sustainability of agriculture. To fulfill this requirement, it is imperative to develop brand-new technologies. application potential nanozymes in plant and environmental sectors progressively becoming apparent a result their effective enzymatic catalytic activity distinctive characteristics nanomaterials, including size, specific surface area, optical properties, thermal properties. Herein, we systematically analyze mechanisms with different enzyme-mimetic activities summarize applications improving crop yields by regulating ROS levels enhancing stress resistance detecting removing hazardous pollutants. Finally, thoroughly challenges faced regarding design, application, economy, biosafety look forward future development directions better serve sustainable
