Glyco-quantum dots: a new luminescent system with multivalent carbohydrate display

5 páginas, 4 figuras, 1 esquema.Nanoclusters of cadmium sulfide covalently bound to biologically significant neoglycoconjugates (glyco-QDs) have been synthesized by means of a single step solution procedure. The neoglycoconjugates confer the QDs water solubility, stability, and biological activity. The nanometer-sized glyco-QDs have been characterized by TEM, EDAX, 1H NMR, UV–vis, and fluorescence spectroscopy. The carbohydrate conjugate nanocrystals can be used as bioactive fluorescence probes for specifically labeling carbohydrate cell receptors.This work was supported by the Ministerio de Ciencia y Technologia (BQU2002-03734).Peer reviewe
