The Synthesis and structural characterization of O2-PPSiI. A Diagrams for synthetic process of O2-PPSiI. B TEM image of O2-PPSi. C The average sizes of O2-PPSi. D The zeta potential of PP and O2-PPSiI. E EDS element mapping images of O2-PIr@Si. F TEM image of O2-PPSiI. G The SEM image of O2-PPSiI. H The SEM of deliberately selected broken O2-PPSiI nanosystem. I The XPS of O2-PPSiI. The inserted data is the high resolution Gd 4d XPS spectra for O2-PPSiI. J The FTIR spectrum of O2-PPSi and O2-PPSiI. K and L The dynamic accumulation of O2-PPSiI and free Gd-DTPA in the tumor monitored by T1WI and T1 mapping-MRI, and significant difference between the muscle and tumor is indicated at P < 0.05 (*) level
