The site-selective assembly of magnetic nanoparticles onto gold nanorods to construct multifunctional Fe3O4–Aurod–Fe3O4 nanodumbbells and Fe3O4–Aurod necklacelike nanostructures with tunable magnetic and plasmonic properties is demonstrated. The probes serve as multiplex sensors for simultaneous magnetic separation, optical detection, and thermal ablation of multiple pathogens (see picture).
