PMMA-Fe₃O₄ for magnetic ablation of bone tumors and bone repair. a PMMA powder, b Fe₃O₄ nanoparticles, c MMA monomer, and d injectable PMMA-6% Fe₃O₄. e Low-magnification SEM image of polymerized PMMA. The scale bar is 50 μm. f High-magnification SEM image of polymerized PMMA. The scale bar is 20 μm. g Low-magnification SEM image of polymerized PMMA-6% Fe₃O₄. The scale bar is 50 μm. h High-magnification SEM image of polymerized PMMA-6% Fe₂O₃. The scale bar is 20 μm. i Thermal images of rabbit legs in the PMMA-6% Fe₃O₄–H group and Tumor-H group. j Enhanced MRI images and coronal reconstructed CT images at each follow-up time point (red arrow: bone destruction and swelling of soft tissue, blue arrow: cortical bone of upper tibial plateau, yellow arrow: area of bone resorption and new bone formation).
