Characterization of GA-Cu@BSA (GCB NDs) and GA-Cu@BSA-DOX (GCBD NPs). a Transmission electron microscope (TEM) image of GCB NDs showing an average size of 8.1 nm. b TEM image of GCBD NPs showing an average size of 40.1 nm. c Dynamic light scattering (DLS) of GCB NDs and GCBD NPs. d The zeta potential of free BSA, free DOX, GCB NDs and GCBD NPs. e The absorbance spectra of free DOX, GCB NDs and GCBD NPs. f Fourier transform infrared (FT-IR) spectra of free DOX, GCB NDs and GCBD NPs. g The release profile of DOX from GCBD NPs at different pH. h The release profile of copper ions from GCBD NPs at different pH. i The fluorescence spectra of different solutions including TA + H2O2, TA + GCBD NPs, H2O2 + GCBD NPs and H2O2 + TA + GCBD NPs (λex = 315 nm)
