New Breakthrough in Nanomedicine – Magnetic Micro Carriers

The standard treatments of cancer like Chemotherapy and Radiation therapy have harmful side effects. They not only kill the malignant cells but also endanger the existence of healthy cells surrounding the tumor.

Scientists have been trying to address this issue of cancer treatment by working on “Targeted Therapy”. The technique involves carrying the potent mode of cancer killing mechanism encapsulated inside a shell.

The mode can be powerful rays or chemicals which would come out of the capsule when the latter is well entrenched into the interiors of the tumor. The technique has been partially effective in its task as of now.

But, a Canadian researcher Prof. Sylvain Martel from the Nanorobotics Laboratory at Polytechnique Montréal has succeeded in sending magnetic spheres inside a living artery.

These spheres contained anti-cancer drugs and the technique of Magnetic resonance imaging was used to send the remedy into its target in an experimental rabbit suffering from liver cancer.The results of this experiment are published in the journal Biomaterials.
