U87MG tumor-bearing mice were intravenously injected with 64Cu-labeled pHPFON-NO/O2 for PET imaging or non-labeled pHPFON-NO/O2 for NIR-II fluorescence and PA imaging. a Representative PET images at 1, 4, 24, 48 h p.i. Tumors are circled with yellow dots. b PET quantification on tumors and selected organs according to a. c Representative NIR-II images at selected time points. Tumors are circled with yellow dots. d Relative NIR-II signals at the tumor regions. e Representative tumoral PA images. f Relative PA signal changes. n = 3 biologically independent animals. Data are presented as mean ± s.d.
