Now very soon it would be possible to image blood vessels and destroy malignant cells in a single integrated system. This system has been created by researchers at Stanford University in which nanoparticles have been designed with a dual function and also offers the benefit of being non toxic and water soluble. Consisting of iron cobalt alloy surrounded by a thin shell of graphic carbon, this nanoparticle has a strong magnetic property which offers high magnetic resonance imaging contrast. Having a graphic shell ensures that the iron cobalt core remains protected and gets functionalized besides absorbing near infrared light. This could certainly help in generating localized heat and trigger therapeutic effect which could help in destroying cancer cells.
