'Smart bombs' to deliver fatal blast to tumours

Abstract:
Nanoscale polymer capsules could one day be used to deliver chemotherapy direct to tumours, leaving adjacent tissue unscathed. The capsules would be designed to rupture when heated by a low-energy laser pulse, delivering their payload right where it is needed.

So Frank Caruso and his team at the University of Melbourne, Australia, are developing an ingenious way of doing this. Their trick is to enclose the drug in polymer capsules that are peppered with gold nanoparticles and attached to tumour-seeking antibodies.
