Figure 4

Photothermal effect and thermal stability.

Notes: (A) The temperature change profiles and (B) thermal images of PBS, free ICG, RGD-IB NPs and RGD-IBA NPs under the irradiation by 808 nm laser (1.0 W/cm2) for 5 minutes. (C) Temperature change of free ICG and RGD-IBA NPs over five cycles of repeated laser irradiation. (D) The fluorescence intensity change of free ICG and RGD-IBA NPs in aqueous solution for 21 days.

Abbreviations: ART, artemisinin; FL, fluorescence; ICG, indocyanine green; PTT, photothermal therapy; NPs, nanoparticles; RGD, arginine-glycine-aspartic acid.
