(A) Iron content in Hela cells after incubated with HPBNs@PAA/PAH/PEG, HPBNs@PAA/PAH/HA-g-PEG and HPBNs@PAA/PAH/HA-g-PEG + free HA. (B) Fluorescence microscopy images of Hela cells after incubation with HPBNs@PAA/PAH/PEG and HPBNs@PAA/PAH/HA-g-PEG and at the PB concentration of 150 μg/mL for 4h: bright field image (1) and fluorescence image (2) of HPBNs@PAA/PAH/HA-g-PEG treated Hela cells, bright field image (3) and fluorescence image (4) of HPBNs@PAA/PAH/PEG treated Hela cells. (C) Fluorescence images of mice bearing Hela tumor at different time points after intravenous injection of IRdye CW800 labeled HPBNs@PAA/PAH/HA-g-PEG and HPBNs@PAA/PAH/PEG, respectively. (D) Fluorescence intensity of tumor and main organs in tumor bearing mice after 24 h injection of above two different NPs, respectively. **: p < 0.01.
