IR783-loaded NBs (IR783-NBs) and its biosecurity. (a) Absorbance spectra were measured in IR783, DPPC, DSPE-PEG-Biotin, and IR783-NBs in ethyl alcohol. The adsorption peak of 200 nm wavelength is caused by DSPE-PEG-Biotin and DPPC. (b) Cytotoxicity of different concentrations of IR-783 in BT-474 cells, as examined by a CCK-8 assay.
