Abstract

We describe the development and characterization of two novel non-blinking 'giant' nanocrystal quantum dot (g-NQD) systems and their application to single-particle tracking in live cells real-time and in three dimensions. The two g-NQDs - CdSe/CdS and InP/CdS - are characterized by a thick shell layer (>10 monolayers of CdS), a quasi-type-II or type-II electronic structure, and extremely suppressed non-radiative Auger recombination and photobleaching, in addition to suppressed blinking. We show that these unique traits make this new class of NQD ideal molecular probes for observing spatio-temporal dynamics of cellular processes.
