Paper Abstract

Energy transfer between semiconductor nanoparticles (quantum dots) and energy donors or acceptors modulates fluorescence, thus serving as a visual indicator of the interaction. Careful choice of conjugate or capping groups can thus make these particles serve as sensors for specific biological processes and as tools for targeted cell killing. Challenges include creation of stable conjugates, delivery to specific cell populations and intracellular regions, and characterization of fluorescence modulation by energy transfer.
