Keywords: , , , ,

Chemical derivatizations with different ligands were perfomed on CdSe/ZnS core-shell quantum dots (QDs). The role of ligands serves to increase water solubility and bio-compatibility of QDs for in-vivo biomedical fluorescence imaging. These QDs were synthesized with various capping agents and optically characterized by using single molecule detection technique to investigate the luminescence properties of single QD such as spectral distribution and blinking.
