Guided modes of surface exciton-plasmon polaritons (SEPPs) in metal-contacted single ZnO nanowires offer a new kind of conversion pathway for the emission of ZnO. The large density of states and effective out-coupling of SEPP guided modes generate emission enhancement in ZnO nanowires.

Highly luminescent CdTe quantum dots, with a photoluminescence quantum yield reaching 60%, were obtained via a facile one-pot microwave irradiation reduction route. They could be used as a fluorescent probe for mercury(II) with a linearly proportional response to the concentration of Hg2+ ion in the range 8.0×10 9 mol/L to 2.0×10-6 mol/L.

SWNT enantiomers are isolated using a chiral surfactant that introduces subtle differences in buoyant density between left- and right-handed SWNTs. Following isolation using density gradient ultracentrifugation, the enantiomer enriched SWNTs are shown to be optically active, thus enabling assignment of high energy excitonic transitions.

Molecular recognition mediated self-assembly of quantum dotantibody conjugates exhibits a concentration dependant sigmoidal kinetic behavior. The parameters of the kinetic behavior may be utilized for quantifi cation of proteomic biomarkers in solution by characterizing non-steady state aggregate population.
