Incorporating CdTe Nanocrystals into Polystyrene Microspheres: Towards Robust Fluorescent Beads

On the Q-dots: Fluorescent polystyrene beads loaded with CdTe quantum dots exhibit excellent pH-independent fluorescence and antisolvent properties (see figure). The beads, which were prepared by miniemulsion polymerization using polymerizable surfactants as both an emulsifier and a phase-transfer agent, offer excellent photostability to the contained CdTe quantum dots due to the hydrophobic nature and compact structure of the polystyrene matrix.
