Abstract

Chemical derivatizations with different ligands were-perfomed on CdSe/ZnS core-shell quantum dots (QDs). The ligands serve a role to increase water solubility and bio-compatibility of QDs in the application of 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 individual QD such as spectral distribution and blinking.
