Institute of Advanced Study in Science and Technology (IASST) have synthesised new magnetic nanoparticles that can be used to treat cancer. This is reported by IANS, a partner of TV BRICS.

The nanocrystalline particles in question are cobalt chromite nanocrystalline particles doped with gadolinium. This compound is capable of heating cancer cells to a temperature of about 46 degrees Celsius, which causes necrosis of tumour tissues.

The heating occurs under the influence of an external magnetic field – this method is called magnetic hyperthermia. It is considered less toxic than classical chemotherapy and radiotherapy, and more affordable than targeted therapy or stem cell transplantation.

However, the researchers note that temperature control in magnetotherapy remains a challenge: the physical properties of the particles make it difficult to heat evenly and safely. The new development brings the method closer to practical application in oncology.

Cancer is a common name for a group of diseases in which the body’s cells begin to divide uncontrollably and form malignant tumours. These cells can invade surrounding tissues and spread throughout the body – a process called metastasis. Cancer treatment depends on the type and stage of the disease and may include chemotherapy, radiation therapy, surgery, and new techniques such as immunotherapy or nanomedicine.
