Abstract (original English)

The present study is aimed at developing an innovative method for efficient cancer cell destruction by exploiting the magnetomechanical actuation (MMA) of Fe-Cr-Nb-B magnetic particles (MPs), which are loaded with clinically approved chemotherapeutic drugs. To achieve this objective, Fe 68.2 Cr 11.5 Nb 0.3 B 20 magnetic nanoparticles were produced by mechanically grinding amorphous ribbon precursors with the same composition. These nanoparticles display high anisotropy, a parallelepipedic shape with an amorphous structure, and a ferromagnetic behavior. MPs were loaded with the antitumoral drugs mitoxantrone (MTX) or doxorubicin (DOX). In our study, we used adipose-derived mesenchymal stem cells and human osteosarcoma cells to test drug-loaded MPs for their biocompatibility, cytotoxicity, and cellular internalization. Further tests involved exposing cells to magnetomechanical actuation and simultaneous MPs-targeted chemotherapy followed by cell viability/death assays, such as MTT and LDH, and live/dead cell staining. Results demonstrate that cancer cell death was induced by the synergistic action of chemotherapeutic drugs and magnetomechanical actuation. The nanoparticle vehicles helped overcome drug resistance, decreasing the high dose of drugs used in conventional therapies as well as the time intervals needed for MMA to affect cancer cell viability. The proposed approach high
