摘要

Recent advances in organometallic synthesis have enabled the size- and shape-dependent preparation of magnetic nanoparticles (MPs), such as Fe_2O_3, Fe_3O_4, Co, and FePt MPs, and semiconducting quantum dots (QDs), such as CdSe-ZnS, CdTe, and CdS QDs, which can be used in a myriad of applications in electronics and biology. Hybrid bifunctional nanoparticles are emerging as useful probes for magnetic-based targeting, delivery, cell separation, magnetic resonance imaging (MRI), and fluorescence-based biolabeling applications. Recently, silica-coated MPs combined with either QDs or dyes have been used in the aforementioned applications. We have developed silica-coating methods for CdSe-ZnS and PbSe QDs, and bifunctional nanoparticles consisting of CdSe-ZnS QDs and γ-Fe_2O_3 MPs. Bioconjugated QDs and multifunctional nanoparticles have been explored for the enhancement of imaging, targeting, and delivery.
