a TEM (scale bar: 500 nm) and b light microscope image of CPDP NPs (scale bar: 20 μm). c Size distribution and d zeta potential of PDP NPs and CPDP NPs. e The size distribution of CPDP NPs within 7 days. f The releasing rate of Ce6 and g the releasing rate of DTX under different conditions (pH 7.4 and pH 5.6, n = 3). h The UV–Vis spectrum of Ce6, DTX, PFP/PLGA and CPDP NPs, respectively. The arrows of CPDP NPs show the characteristic peaks of Ce6 and DTX, indicating the effective encapsulation of both materials. i The TEM result of two nanoparticles. The PFP/PLGA nanoparticle exhibits the thin shell and the round core (left). The CPDP nanoparticle encapsulated both Ce6 and DTX shows the much thicker shell and the oval-shaped core (right)
