Magnetic Hyperthermia Performance of Fe-, Ni-, and Co-Loaded Multi-Walled Carbon Nanotubes for Biomedical Applications

Magnetic hyperthermia has emerged as a promising therapeutic strategy for localized cancer treatment through magnetically induced heating. In this study, multi-walled carbon nanotubes loaded with iron (Fe), nickel (Ni), and cobalt (Co) magnetic nanoparticles were evaluated as potential hyperthermia agents. Building upon previous investigations of magnetic functionalization and thermal stability, the present work analyzes the expected heating behavior of magnetic carbon nanotube systems under alternating magnetic fields. Structural characteristics, magnetic responsiveness, and thermal conversion capabilities were examined to identify the most suitable nanostructures for biomedical heating applications. The results indicate that magnetic nanoparticle encapsulation within carbon nanotubes provides efficient heat generation while preserving structural integrity. Among the investigated systems, Fe-loaded nanotubes demonstrate the most favorable balance between magnetic response, biocompatibility, and thermal performance, highlighting their potential for future cancer hyperthermia therapies.
