Figure 4

(a) FT-IR spectra of PTX, MPDA-PEG and PTX-loaded MPDA-PEG nanoparticles. (b) Nitrogen adsorption-desorption isotherms and (c) pore size distribution curves of MPDA-PEG-190 and PTX-loaded MPDA-PEG-190. (d) PTX release performance of PTX-loaded MPDA-PEG-190 with or without NIR irradiation (808nm, 2 W cm−2, 5 mins) at an interval of 2 hrs.

Abbreviations: PTX, paclitaxel; MPDA-PEG, polyethylene glycol-modified mesoporous polydopamine; NIR, near Infrared.
