| Abstract Scope |
The inherent heavy metal toxicity of fluorescent binary quantum dots (QDs) despite their excellent optical properties has limited their biological applications. This has shifted the research focus towards toxic-metal free chalcopyrite ternary QDs such as AgInS2 (AIS), CuInS2 (CIS), ZnInS (ZIS) QDs e.t.c. Among these QDs, ZIS has been given less attention despite its advantages over other conventional ternary QDs. This is attributed to the difficulty in producing zero dimensional (0D) ZIS via aqueous synthetic route compare to other morphologies. We herein report facile and ecofriendly aqueous synthesis, properties and cellular activity of 0D ZIS. The synthesis was carried out via a reflux method using thioglycolic acid (TGA) and gelatin as capping ligand and stabilizer. The temporal evolution of the optical properties was investigated by varying the pH, TGA concentration, amount of gelatin, Zn/In ratio and sulfur concentration. The as-synthesized QDs show excellent biocompatibility towards normal and cancerous cells. |
