Figure 1

TEM images of AuNCs (a) and Cu-doped AuNCs (1% Cu); (b). The scale bar is 10 nm; (c) Histogram of size distribution of Cu-doped AuNCs (1%) and AuNCs calculated from TEM images; (d) hydrodynamic diameter (HD) of Cu-doped AuNCs (1%) in PBS, measured by dynamic light scattering (DLS); (e) UV-vis absorbance and fluorescence emission spectrum of Cu-doped AuNCs (1% Cu); (f) CD spectra of pure HSA and Cu-doped AuNCs (1% Cu).
