a Schematic illustration of NIR light-triggered drug release from the nanoparticle containing Os and BC (Os/BC NP). b Size distribution of various nanoparticles. c TEM image of Os/BC NPs. The test was independently repeated in triplicates with similar results. d Normalized absorption of BC NPs and Os/BC NPs in aqueous solutions. The red area indicates the NIR window. e Percentage of uncleaved BODIPY-Cb and released Cb from Os/BC NPs upon 690 nm light irradiation for 0–30 min. f Percentage of uncleaved BODIPY-Cb and released Cb from BC NPs upon 690 nm light irradiation for 0–30 min. Data are presented as mean ± SD, n = 3 independent experiments. Source data are provided as a Source Data file.
