Stability tests. (a) Photostability of Hb/Pt NCs after ultraviolet (UV) irradiation for up to 2 hours with λex/λem = (320 nm)/(450 nm). (b) The pH effect on the fluorescence emission intensity of Hb/Pt NCs; [PBS] = 10 mM. (c) Emission spectra of Hb/Pt NCs in the absence and presence of 1 M NaCl. (d) Zeta potential of Hb/PtNCs monitored with time.
