Address correspondence to

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 8.010 9 mol/L to 2.010-6 mol/L.


Isolation of Single-Walled Carbon Nanotube Enantiomers by Density Differentiation

Alexander A. Green, Matthew C. Duch, and Mark C. Hersam()
Department of Materials Science and Engineering and Department of Chemistry, Northwestern University, Evanston, Illinois 60208-3108, USA

DOI 10.1007 s12274-009-9006-y

Nano Res (2009)2:69-77

Address correspondence to

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.


Kinetics of Molecular Recognition Mediated Nanoparticle Self-Assembly

Chinmay Soman1 and Todd Giorgio2()
1 Interdisciplinary Program in Materials Science, Vanderbilt University, 201 West End Avenue, Nashville, TN 37240, USA
2 Department of Biomedical Engineering, Vanderbilt University, 201 West End Avenue, Nashville, TN 37240, USA

DOI 10.1007 s12274-009-9005-z

Nano Res (2009)2:78-84

Address correspondence to

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.
