Characterization of DOX@MOF-COD@CS nanosystem. A TEM micrographs of the MOF, MOF-COD, CS and DOX@MOF-COD@CS nanoparticles. B XRD spectra of NH2-MIL-88B. C Peroxidase-like properties of MOF-COD. D SDS-PAGE images. 1: Marker, 2: COD (~ 50KDa), 3: MOF, 4: MOF-COD (~ 50KDa) without free COD. E FT-IR spectra of CS shell, DOX@MOF-COD@CS, MOF and DOX@MOF-COD + CS. F Infrared spectra of CS response to GSH cracking. G In vitro release curves of DOX. Data are presented as mean ± SD, ***P < 0.001
