PEGylated liposome coated QDs/mesoporous silica core-shell nanoparticles for molecular imaging

Abstract

This paper describes the synthesis and application of PEGylated liposome-coated quantum dots (QDs)/mesoporous silica core–shell nanoparticles (NPs) for molecular imaging. This system increases biocompatibility and stability of QDs, thus improving the imaging effects in labeling of cancer cells. © 2011 The Royal Society of Chemistry.
