(A) HCPT@HPBNs@PAA/PAH/HA-g-PEG NPs suspended in plasma for different time; (B) In vitro release pattern of HCPT from HCPT@HPBNs@PAA/PAH/HA-g-PEG NPs at 37oC and pH 7.4; (C) Temperature elevations of HCPT@HPBNs@PAA/PAH/HA-g-PEG NPs at different concentrations under NIR laser irradiation (808 nm, 1.5 W); (D) HCPT release profile from HCPT@HPBNs@PAA/PAH/HA-g-PEG NPs with three cycles of laser on/off. All release studies were performed in triplicate.
