A Study on Magnetic Nanoparticles Based on Mossbauer Spectroscopy for Application in Hyperthermia

In recent years, the synthesis and characteristics of nanoparticles have significantly advanced, leading to a growing interest in researchers studying new magnetic nanoparticles in various application fields. Hyperthermia is a method that utilizes magnetic nanoparticles to inject into cancer cells and utilizes the heat generated by the magnetic nanoparticles under an alternating magnetic field to destroy the cancer cells. To achieve this purpose, magnetic nanoparticles with almost zero coercivity and characteristics of superparamagnetism or single-domain ferri-or ferromagnetism and minimal size are required. This review paper is based on the Mossbauer spectroscopy technique to observe magnetic nanoparticles at the nano-scale. It focuses on the research of heat generation and magnetic properties of various forms of magnetic nanoparticles and introduces the research trends of magnetic nanoparticles that can potentially be applied in hyperthermia.
