Аннотация:The best of both worlds: Multifunctional Fe3O4@[email protected] shell nanoparticles (see scheme; Fe3O4 is black, polymer is blue, gold shell is brown) display good dispersibility and stability in aqueous solution. Strong magnetization and good NIR absorption are preserved in the core–shell structures. These features should facilitate biomedical applications, combining the benefits of MRI diagnosis, magnetically targeted delivery, and photothermal ablation.
