Gold Nanorod/Fe3O4 Nanoparticle “Nano‐Pearl‐Necklaces” for Simultaneous Targeting, Dual‐Mode Imaging, and Photothermal Ablation of Cancer Cells

Abstract
Gold and pearls: Multifunctional nanoparticles, each composed of a single, amine-modified gold nanorod, decorated with multiple “pearls” of Fe3O4 nanoparticles capped with carboxy groups, are prepared. Their effectiveness in simultaneous targeting, dual-mode imaging, and photothermal ablation of breast cancer cells is demonstrated.
