Multifunctional magnetic and fluorescent core–shell nanoparticles for bioimaging

Abstract

Novel magnetic and fluorescent core–shell nanoparticles have been fabricated, which exhibit superparamagnetic behavior and emit strong near-infrared fluorescence. The nanoparticles are highly biocompatible and can be internalized into cells with nucleic accumulation via strong interaction with nucleic acids, implying potential applications in the biomedical field.
