Bifunctional nanoparticles with superparamagnetic and luminescence properties

Abstract

We report for the first time the synthesis of CdSe@Fe₂O₃ core/shell nanoparticles by a one-step seeded-growth approach. These nanoparticles not only retain their individual semiconducting and magnetic functionalties, but also exhibit some new properties which are affected by the coating components. These bifunctional CdSe@Fe₂O₃ nanoparticles might find potential applications in biosensing and in biomedical research.
