Twin nanoparticle shown effective at targeting, killing breast cancer cells

A team of investigators at Brown University has developed a novel way to treat a class of breast cancer cells. The team has created twin nanoparticles that specifically targets the Her-2 tumor cell and unload a cancer-fighting drug directly into it. The result is a boost in antitumor activity while minimizing side effects. The findings of this study have been published in the Journal of the American Chemical Society.
