PA imaging in vitro and in vivo. PA images (a) and PA values (b) of IMTP-Fe3O4-PFH NPs at different Fe concentrations in vitro. c In vivo PA images of the hearts in model rats after intravenous injection of IMTP-Fe3O4-PFH NPs or Fe3O4-PFH NPs pre-operation, baseline, 10 min, and 60 min after injection. d The changes of PA signal intensity in the heart region at the corresponding time point
