Then, we synthesized the magnetic nanoparticles like Fe3O4, γ-Fe2O3 and α-Fe2O3 with different sizes and shapes and nanocomposites with core-shell structures like Au-Fe3O4 and Fe3O4-TiO2. We studied the cancer cell killing effects under three distinct conditions, a) only CW or pulsed alternating-current (AC) magnetic-field induction, b) only photoirradiation and c) combined CW or pulsed AC magnetic-field induction and photoirradiation conditions. For HeLa cancer cells adopted as a model to investigate the thermal-photocatalytic cancer cell killing efficiency of as-synthesized nanomaterials, almost 100% cancer cells were destructed under combined (CW or pulsed) AC magnetic-field induction and photoirradiation conditions. We got fruitful information on the sound-waves detection induced by pulsed AC magnetic-fields for aqueous solution including magnetic nanoparticles.},
