Facile Synthesis of Superparamagnetic Fluorescent Fe₃O₄/ZnS Hollow Nanospheres

Abstract

A very simple strategy for the synthesis of superparamagnetic and fluorescent Fe(3)O(4)/ZnS hollow nanospheres is presented. These hollow nanospheres are not only nontoxic with a highly porous shell and have diameters of <100 nm but also exhibit very good magnetic resonance and fluorescence.
