A The morphology and size distribution of DIMP. B Zeta potential of ZIF-8, DOX, ICG and DIMP, and data were expressed as mean ± SD (n = 3). C Diameter distribution and the PDI change of DIMP under different incubation time. D UV–Vis absorption spectrum and E Fluorescence emission spectrum of DOX, ICG and DIMP. F The release curve of DOX under different pH conditions. G XPS patterns of the DIMP. H TGA curves of DIMP and ZIF-8. I Infrared thermal image of DIMP with different concentration and under different irradiation time of the 808 nm laser (1.5 W/cm2). J Photothermal heating curves of DIMP with different concentration under NIR laser (808 nm, 1.5 W/cm2). K Photothermal heating curve of DIMP with the same concentration and under different power of NIR laser (808 nm). L The photothermal recycle curve of DIMP
