Scientists have developed a new nanomaterial composed of magnetic nanoparticles and trislic acid, which is intended for the treatment of bone defects after surgical removal of a tumor.[2] Magnetic nanoparticles have the ability to absorb electromagnetic radiation and convert it into heat, while the application of an alternating magnetic field heats the affected tissue to a temperature between 42°C and 45°C, causing irreversible changes in cancer cells.[4] At the same time, healthy tissue is affected at least thanks to a sufficient vascular bed that can remove excess heat.[4] Trisolic acid is released from the material especially during the first hours after contact with the biological environment and has antioxidant, anti-inflammatory and anti-tumor effects.[2] The presence of magnetic nanoparticles in the material affects its physical and biological properties, including antibacterial action.[2] The ratio of magnetic particles and trislic acid can be changed, which can regulate the rate of degradation of the material and the intensity of its biological effects.[2] The researchers plan to further investigate the behavior of these magnetic "scaffolds" in the presence of an external magnetic field to verify the possibilities of targeted therapy and monitoring bone healing in a living organism using imaging techniques.[2]
