Schemes of AKI animal models and corresponding biodistribution studies using ⁸⁹Zr‐DFO‐SeCQDs. a) Method used to establish RM‐AKI. b) Coronal and axial slices of PET images after administering ⁸⁹Zr‐DFO‐SeCQDs in RM‐AKI model and c) corresponding ROI analysis. d) Ex vivo biodistribution studies in RM‐AKI mice. e) Method used to establish CP‐AKI. f) Coronal and axial slices of PET images after administering ⁸⁹Zr‐DFO‐SeCQDs in CP‐AKI model and g) corresponding ROI analysis. h) Ex vivo biodistribution studies in CP‐AKI mice. In (c–e,g), data represent mean ± s.d. from three independent replicates.
