In this work alginate nanocomposite fibers modified with magnetite were investigated as prospective material for bone tissue regeneration after tumor resection. In the first stage of the research the morphology of composite fibers and their chemical composition were evaluated. Determination of the mechanical properties of the nanocomposite materials indicated that magnetite does not improve the strength of the nanocomposites. A slight increase of Young’s modulus was observed only for composite fibers with a lower concentration of nanoadditive. Weekly and monthly incubation of fibers in distilled water indicates the release of magnetite from the material. This result is optimistic in terms of the applicability of these materials, not only for tissue regeneration, but also to destroy cancer cells using the external magnetic field.
