Highly luminescent near-infrared (NIR) emitting CdTe/CdSe quantum dots (QDs) were prepared through a fast and convenient method, and a new type of multivalent polymer ligands was used as the surface substituents to prepare highly stable hydrophilic QDs with small sizes. The well-defined CdTe/CdSe QDs were characterized by transmission electron microscopy(More)
Targeted quantum dots have shown as an analytical and imaging tool for cancer detection and molecular imaging. Aptamers have recently been demonstrated as ideal candidates for molecular targeting applications. In the present work, quantum dots (QDs) were encapsulated with functional poly(ethylene glycol)-phospholipids to improve their solubility in water(More)
Highly luminescent near-infrared (NIR)-emitting gold nanoclusters (Au NCs) protected by glutathione with ultra-small size were prepared at high temperature following with a further natural etching at room temperature. The optical and surface properties of Au NCs were monitored by ultraviolet-visible and photoluminescence (PL) spectra, high-resolution(More)
