DELEHANTY, JAMES B. ; MEDINTZ, IGOR L. ; PONS, THOMAS ; BRUNEL, FLORENCE M. ; DAWSON, PHILIP E. ; MATTOUSSI, HEIDIWe demonstrate the use of self-assembled luminescent semiconductor quantum dot (QD)-peptide bioconjugates for the selective intracellular labeling of several eukaryotic cell lines. A bifunctional oligoarginine cell penetrating peptide (based on [...]texto impreso
We present a single particle fluorescence resonance energy transfer (spFRET) study of freely diffusing self-assembled quantum dot (QD) bioconjugate sensors, composed of CdSe-ZnS core-shell QD donors surrounded by dye-labeled protein acceptors. W[...]texto impreso
FU, YING-SONG ; DU, XI-WEN ; KULINICH, SERGEI A. ; QIU, JIAN SHENG ; QIN, WEN-JING ; LI, RUI ; SUN, JING ; LIU, JIMThe aqueous dispersion of ZnO quantum dots (QDs) with strong blue emission (quantum yield of 76%) was synthesized through a simple solution route. The water stability of such QDs is provided by the hydroxyl groups on their surface, and the stron[...]Article : texto impreso

Water-soluble and stable quantum dots (QDs), CdTe and CdZnSe, are applied for ultrasensitive Pb2+ detection. These QDs are capped with glutathione (GSH) shells. GSH and its polymeric form, phytochelatin, are employed by nature to detoxify heavy [...]texto impreso
NA, HYON BIN ; LEE, IN SU ; SEO, HEONJIN ; PARK, YONG IL ; LEE, JUNG HEE ; KIM, SANG-WOOK ; HYEON, TAEGHWANWe report the simple synthesis of poly(ethylene glycol) (PEG)-derivatized phosphine oxide ligands for water-dispersible metal oxide nanocrystals.
