Fabrication of quantum dots for biomedical applications
This study utilised a bottom-up direct aqueous-phase synthesis technique to synthesize high quality Cadmium-Tellurium (CdTe) Quantum Dots capped with Mercaptopropionic acid (MPA). Direct aqueous-phase synthesis is a two-step technique which involves the preparation of the Cd and Te precursors and th...
