Nano scale smartbombs

Nano "TNT" destroys cancer cells without collateral damage.

Triton BioSystems' TNT (Targeted Nano-Therapeutics) consists of magnetized iron-oxide particles attached to monoclonal antibodies, which are engineered versions of human immune system proteins that seek out a specific protein.

The TNT attacks cancer in three steps.

First, the patient receives a simple infusion containing trillions of bioprobes, each of which is a nano-scale magnetic sphere bound to an antibody. Once in the bloodstream, the bioprobes seek out and attach to cancer cells. Finally, the doctor switches on a magnetic field in the region of the cancer, which causes the bioprobes to heat up, killing the cancer cells within minutes.azonano.com

Not toxic like chemo or radiation treatments.

In the March issue of the Journal of Nuclear Medicine, Sally Denardo, a professor of internal medicine and radiology at UC Davis, described how this treatment resulted in slower tumor growth rates and no toxic side effects.

"This is not just intriguing basic science," she said, adding that the therapy could be combined with other treatments like chemotherapy, to give patients a better shot at beating cancer. "It could have a major impact," she said.Reuters
