Cobalt chromite magnetic nanoparticles: New magnetic system developed using nanocrystalline cobalt chromite magnetic nanoparticles to treat cancer via magnetic hyperthermia.

• About Cobalt Chromite Magnetic Nanoparticles: Cancer is one of the most threatening diseases for humanity.

  o Includes radiation therapy, chemotherapy, targeted therapy, and stem cell transplant.

  o Chemotherapy and radiation may cause nausea, exhaustion, hair loss, infection risk.

  o Enables targeted heat generation (hyperthermia) with fewer side effects.

  o Magnetic field used to control heat generation externally.

  o Synthesis method: Used chemical co-precipitation route with varying Gd dopant contents.

  o Heat generation: Nanoparticles in fluid form generate heat under alternating magnetic field.

  o Therapeutic effect: Raises temperature to 46°C, causing necrosis in cancer cells.

  o Function: Nanoparticles act as superparamagnetic nano-heaters for magnetic hyperthermia.
