Preparation of DNA-Functionalised CdSe/ZnS Quantum Dots

We functionalised core-shell CdSe/ZnS quantum dots (QDots) with short-chain 3-mercaptopropionic acid (3MPA) to render these nanocrystalline semiconductor water-soluble. The ligand-exchange reaction was significantly improved with the use of an organic base to first remove the thiolic hydrogen. Non-b...
