Surface modified fluorescent quantum dots with neurotransmitter ligands for potential targeting of cell signaling applications

- CdS quantum dots were prepared using aminoacids neurotransmitters as capping-ligands.
- Quantum dots/aminoacid bioconjugates were prepared with particle size of about 3.0 nm.
- The bioconjugates were produced at room temperature via a single-step aqueous colloidal chemistry.
- Novel nano-hybrid systems were developed for potential neurobiological applications.
