Abstract

Magnetic nanoparticles serve as essential tracers in biomedical applications, including diagnostics such as magnetic particle imaging (MPI) and therapies like magnetic fluid hyperthermia (MFH). However, meeting the physicochemical requirements of both applications within a single nanoparticle system remains challenging. Magnetosomes, a novel class of magnetic iron oxide nanoparticles biosynthesized by bacteria, offer a promising solution, as their magnetic properties can be tuned through genetic engineering. Here, magnetosomes are investigated for dual functionality as MPI tracers and MFH heat mediators, highlighting their potential as a theranostic platform.
