(a) Uptake value [number (N) of internalized AuDD particles per MDA-MB-231 cell for 8 h of incubation at 37 °C] of the AuDD-based samples measured using an ICP-MS (mean ± SD, n = 3, ** p < 0.01 compared to AuDD at pH 7.4). (b) Flow cytometry analysis of MDA-MB-231 cells (incubation time: 8 h) treated with free Ce6, Ce6-tagged AuNP, BSA@CNf-Ce6, or AuDD/BSA@CNf-Ce6 at pH 7.4 and 6.8. (c) The hyperspectral images of the MDA-MB-231 cells incubated with untreated (control) or AuDD/BSA@CNf-Ce6 at pH 7.4 and 6.8.
