Kinetic release profile of DOX from the HIDPPDNEs under NIR laser irradiation in vitro. The cumulative release curve of the HIDPPDNE-entrapped DOX (black curve) under NIR laser irradiation was established by measuring the concentrations of DOX in the supernatant through UV–Vis spectrometry (λ = 485 nm) after irradiated for 0, 10, 30, 60, 120, 180, 240, and 300 s. The NIR exposure was performed using an 808-nm laser with an intensity of 6 W/cm2. The red curve indicates the temperature of the HIDPPDNE medium at each time point while the concentration of released DOX was detected. Values are mean ± s.d. (n = 3)
