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.
