CDT capacity and targeting abilities of HA‐CD@MOF NPs. A) H₂O₂‐generating ability of the HA‐CD@MOF NPs with or without HAD in solutions with GSH (10 mm); n = 3. B) The effect of GSH (10 mm) and H₂O₂ (10 mm) on MB degradation. C) MB degradation rate under different conditions in solutions with GSH (10 mm) and H₂O₂ (10 mm). D) Electron spin resonance spectra of DMPO mixed with HA‐CD@MOF NPs under different conditions (i, without GSH and HAD; ii, with GSH and HAD). E) The GSH‐depleting ability of HA‐CD@MOF NPs at different concentrations, n = 3. F) CLSM images of HUVECs and 4T1 cells after coincubation with CD@MOF NPs or HA‐CD@MOF NPs for various times (scale bars: 50 µm). G) FCM analysis of the intracellular uptake of CD@MOF NPs or HA‐CD@MOF NPs in 4T1 cells and HUVECs for 0.5, 1, 2, and 4 h. Results are presented as means ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
