Abstract |
Herein, we have presented a unique strategy for aqueous synthesis of semiconductor
CuInS2 QDs which showed multiple fluorescence. These synthesized CuInS2 QDs were prepared
in aqueous media with biocompatible glutathione (GSH), as capping ligand and stabilizer, while
the fluorescence and crystallinity were controlled by varying the reaction time. The investigation
of various other experimental parameters including precursor’s concentration, effect of pH, and stability
of QDs has also been carried out. These QDs were characterized by XRD, TEM, and FT-IR.
Meanwhile, optical properties of as synthesized QDs were also investigated by fluorescence spectroscopy.
Furthermore, the synthesized QDs were also less cytotoxic and maintained remarkable
cell viability up to 100 lg/mL. When bioconjugated with Arginyl-glycyl-aspartic acid (RGD)
moiety, the obtained CuInS2-RGD QDs have shown higher biocompatibility and good bioimaging
performance.
