摘要

Abstract

Integration of biocompatibility with superparamagnetic Fe

nanoparticles and luminescence rare earth complexes Eu(AA)

Phen was carried out to form bifunctional nanospheres for using in bioimaging applications. The nanospheres Poly(MMA-HEMA-Eu(AA)

Phen)/Fe

exhibit magnetic and fluorescent properties that are favorable for the use in drug delivery

magnetic separation and MR imaging for biomedical research. The TEM and SEM studies reveal that the bifunctional nanospheres have core-shell structure

in a spherical shape with a size ranging from 140 nm to 180 nm. In MRI experiments

a clear negative contrast enhancement in

images and the

In vivo

magnetic and fluorescence resonance imaging results suggest the nanospheres are able to preferentially accumulate in liver and spleen tissues to allow dual-modal detection of cancer cells in a living body.
