Synthesis and fabrication of CNTs/Fe3O4@Pdop@Au nanocables by a facile approach

Abstract

Multifunctional nanocables were prepared by directly welding superparamagnetic Fe₃O₄ nanoparticle decorated CNTs and Au nanoparticles together with polydopamine (Pdop) as “glue” in a facile but effective way. Additionally, the size and density of the Au nanoparticles can be easily controlled by different chemical approaches. Moreover, these core–shell nanocables can be a versatile platform for multiple applications.
