| Summary: | Plasmonic nanostructures provide a versatile platform for modulating nanoscale energy transfer processes. Herein, we report a magnetoplasmonic nanofluid comprising core-shell MnFe2O4@Fe3O4 nanocubes and gold nanorods that exhibits significantly enhanced magnetic hyperthermia performance under kHz-range alternating magnetic fields. A marked increase in heating efficiency, up to 50% higher specific absorption rate (SAR) compared to the ferrite-only control samples, was observed when the plasmon resonance of the Au nanorods aligned with near-infrared optical transitions of the ferrite nanocubes. This enhancement is attributed to the polariton-like hybridization phenomenon in the near field. Such findings open potential avenues for engineering multifunctional nanomaterials for targeted cancer therapy and theragnostic applications. |
