In vivo MRI performance and CDT ability of CuS:Gd NPs. a T1-weighted MR images of mice at different time points after the injection of CuS:Gd NPs (25 mg/kg) and the commercial Magnevist (Gd-DTPA) for comparison, confirming the well MRI behavior of CuS:Gd NPs in vivo. b Time course change of the tumors volume of different groups (saline group and CuS:Gd NPs group), indicating the excellent CDT performance of CuS:Gd NPs in vivo. (n= 6, mean ± SD). c Body weights change of the 4T1 tumor-bearing Balb/c mice during CDT process. (n= 6, mean ± SD). d H&E staining of the tumor tissues from the 4T1 tumor-bearing Balb/c mice from different groups. Scale bar: 50 μm. e H&E staining of the main organs after the treatment of CuS:Gd NPs
