How nanoparticles could change the way we treat cancer

Ninety-nine percent of cancer drugs never make it to tumors, getting washed out of the body before they have time to do their job. How can we better deliver life-saving drugs? Cancer researcher Joy Wolfram shares cutting-edge medical research into nanoparticles -- tiny particles that could be used to deliver drugs accurately to tumors -- and explains how they could keep drugs in the body longer to attack malignant cells.
