Illustration of the synthesis of fluorescent GSH–Au/Ce NCs. Mixed with a certain concentration of glutathione and HAuCl4 until the solution became colorless, then the mixture was placed in a water bath with 90°C for two hours, and a certain concentration of Ce(NO3)3 aqueous solution was added immediately, the mixture was blending and heating in water bath with 90°C for another one hour. The separated and purified Au/Ce NCs were applied in bioimaging and measured by fluorescence spectrometer and transmission electron microscope.
