Nanoparticle polymer capsules loaded with an anti-cancer drug specifically attach themselves to prostate tumor cells and use their chemotherapy to destroy cancer, according to the latest collaborative research led by Omid Farokhzad, an assistant professor of anesthesia at Brigham and Women's Hospital and Harvard Medical School.

In experiments performed with mice, researchers used custom designed polymer nanoparticles derived from FDA-approved biodegradable and biocompatible components. The nanoparticles homed in on, and then entered, malignant cells, delivering lethal doses of chemotherapy while leaving healthy cells unaffected.
