A, B The absorption and C, D fluorescence emission spectra of molecular fluorophores IR-26, IR-FTT, IR-FCD, and IR-FCD-Ts in dichloromethane DCM and water solutions. E TEM images of IR-FCD-Ts NPs distribution analysis. F Hydrodynamic diameter size distribution of IR-FCD-Ts NPs. G Cumulative release of IR-FCD-Ts after incubating nanoparticles in GSH aqueous solutions of different concentrations for varying times. Error bars: mean ± SD (n = 3). H Heating curves of IR-FCD-Ts NPs at various concentrations upon 1064 nm laser irradiation. I Heating curve of IR-FCD-Ts NPs (30 µM) under 1064 nm laser irradiation of different power densities. J The photothermal conversion efficiency and K photothermal stability of IR-FCD-Ts NPs. L ROS production under 1064 nm laser irradiation with different times (I0 and I represent the emission intensities of DCF at 525 nm before and after irradiation, respectively). Error bars: mean ± SD (n = 3)
