We report here a Green method for the synthesis of fluorescent gold nanoclusters using dithiothreitol (DTT) as both a capping agent and reducing agent at 22 °C and pH 8. The physical and chemical properties of the synthesized AuNCs@DTT were studied by TEM and UV-vis absorption, fluorescence, and X-ray photoelectron spectroscopy. AuNCs@DTT recognizes cupric… CONTINUE READING
