(Invited) Investigation into the Photophysics and Diffusion Properties of Water Soluble Quantum Dots Using Fluorescence Correlation Spectroscopy

Because of their superior photostability and fluorescence quantum yield, quantum dots are of great interest for biological applications. Unfortunately, most commercial quantum dots require a surfactant solubilizing layer to disperse in aqueous media. This significantly increases their effective diameter and limits their appeal for single molecule studies. Thus Carboxylate capped CdTe nanoparticles, which are water soluble, represent an …
