Magnetically Targeted Doxorubicin Delivery Using Functionalized Multi-Walled Carbon Nanotubes: A Conceptual Assessment Based on Magnetic Nanotube Platforms

Targeted drug delivery remains one of the most promising applications of multifunctional nanomaterials in oncology. Carbon nanotubes provide unique opportunities for combining drug transport, magnetic targeting, and localized therapeutic action within a single nanoplatform. Building upon previously reported structural, magnetic, thermal, and hyperthermia investigations of magnetic multi-walled carbon nanotubes (MWCNTs), the present work evaluates their potential use as carriers for magnetically guided doxorubicin delivery. The analysis focuses on the physicochemical properties required for efficient drug loading, transport, magnetic localization, and controlled release. The results indicate that magnetic carbon nanotube systems possess the structural and functional characteristics necessary for future development as multifunctional theranostic platforms integrating drug delivery, magnetic targeting, and hyperthermia-assisted cancer treatment.
