Penetration of drugs delivered by PFP@PDM-PEG into 4T1 tumor spheroids and the tumor parenchyma. A In vitro confocal microscopy images of the penetration of FITC-labeled PFP@PDM-PEG into a 4T1 tumor spheroid model and C the corresponding fluorescence intensities. Images were obtained from the top to the middle of the spheroids every 10 mm; scale bar: 50 μm. B CLSM images of the distribution of DiI-labeled PFP@PDM-PEG in tumor cryosections and (D) the corresponding fluorescence intensities; scale bar: 1 mm (n = 3, t-test, ***p < 0.001)
