Russian scientists have developed a simple and affordable way to create nanoparticles that can be used to diagnose and treat cancerous tumors. This innovation gives up expensive and harmful substances. Experts from MISIS University played an important role in this work.
Recently, magnetic nanoparticles are increasingly used in biomedicine, especially in cancer treatment. Their small size allows them to penetrate deep tissue layers and their magnetic properties make them controllable by external magnetic fields. Of particular interest are cobalt ferrite (CoFe2O4) nanoparticles, which are known for their stability. But it is difficult to produce in rod form, which is promising for medicine.
Researchers from MISIS University, RKhTU im. DI Mendeleev and RNIMU them. NI Pirogov developed a method for forming rod-shaped pure cobalt ferrite nanoparticles. This technology is not only cost-effective and does not require expensive materials, it is also versatile, making it easy to create other types of nanoparticles for different purposes.
The forming process is based on several steps, including preparing a matrix from iron oxyhydroxide and forming a spinel ferrite. Synthesized nanoparticles showed high efficiency in the destruction of cancer cells in experiments. These nanoparticles can also be used as an MRI contrast agent. The scientists plan to improve this method further by adding specific molecules to control the activity of cell receptors using magnetic fields.
