"By harnessing the body's blood-clotting system, researchers have designed nanoparticles that scout out tumours and then call in a second type of nanoparticle to deliver cancer-killing drugs.
Sangeeta Bhatia, a bioengineer at the Massachusetts Institute of Technology in Cambridge, and her colleagues found that using the two nanoparticles in tandem in mice increased the amount of drug delivered to a tumour by 40-fold relative to controls. Tumours in these mice stopped growing, whereas those in mice that received only one type of nanoparticle did not."
