A magnetic and fluorescent mesoporous Fe3O4/SiO2/CdTe nanoprobe with well-defined core-shell nanostructures was prepared.This multifunctional nanoprobe was synthesized through a novel method mainly including two steps.The first step involves the controlled growth of mesoporous silica layer onto the surface of Fe3O4 nanoparticle using tetraethyl orthosilicate as silica source, cationic surfactant cetyltrimethylammonium bromide as template, and 1,3,5-triisopropylbenzene/decane as pore swelling agents.
