Synthesis and characterization of photonanomedicine. A Schematic depiction of the fabrication of photonanomedicine. B A representative TEM image of hydrophilic amino-functionalized UCNP and PpIX modified UCNP. C Fourier transform infrared (FTIR) spectra of amino-functionalized UCNP (black curve), PpIX (red curve) and UCNP-PpIX (green curve). D Luminescence emission spectra of UCNP (blue line) and UCNP-PpIX (black line) that were irradiated by a NIR laser. E Hydrodynamic sizes of CA-lacking photonanomedicine and photonanomedicine upon 980 nm NIR irradiation (2 W/cm2) for various time periods (insert: a representative TEM picture of photonanomedicine after 980 nm NIR irradiation for 30 min). F Consumption of DPBF over time after different treatments. G Absorbance changes of DPBF treated with photonanomedicine after 980 nm NIR laser irradiation for various time periods. Data were presented as means ± SD, ***p < 0.001, compared with five other control group
