DOX loading and releasing.

Notes: (A) UV-vis absorbance spectra of DOX, Fe₃O₄@PDA-PEG-EGFR NPs, and Fe₃O₄@PDA-PEG-EGFR-DOX NPs. (B) DOX release from Fe₃O₄@PDA-PEG-EGFR NPs at different pH over 36 h. (C) NIR-triggered DOX release from Fe₃O₄@PDA-PEG-EGFR-DOX NPs. The samples at different pH were irradiated with an 808 nm NIR laser (0.6 W/cm²) at different time points indicated by the arrows. Error bars mean standard deviations (n=3).

Abbreviations: DOX, doxorubicin; NIR, near-infrared; UV-vis, ultraviolet visible; PDA, polydopamine; PEG, polyethylene glycol; NP, nanoparticle.
