Magnetic Polymer Nanocomposites for Biomedical Applications

Magnetic nanoparticle–conductive polymer composites represent a promising class of multifunctional materials for biomedical applications. Among them, Fe₃O₄–polyaniline (PANI) composites have gained attention due to their unique combination of magnetic responsiveness, electrical conductivity, and biocompatibility. This explores synthesis strategies, biomedical applications such as drug delivery, and compares Fe₃O₄–PANI systems with other magnetic nanoparticle–polymer composites. The discussion highlights the advantages of Fe₃O₄ emphasizing its reduced cytotoxicity and multifunctionality.
