Water dispersible semiconductor nanorod assembliesvia a facile phase transfer and their application as fluorescent biomarkers

Abstract

We demonstrate the formation of water dispersed nanorod assemblies by phase transfer of semiconductor (CdS, CdSe, CdTe) nanorods from the organic to the aqueous using pluronic triblock copolymers. On phase transfer, the randomly dispersed nanorods in the organic medium close pack in the form of discs encapsulated in the hydrophobic core of water dispersible micelles. The assemblies showed excellent cellular uptake exhibiting membrane and cell specific fluorescence at low light intensity under confocal microscopy.
