When her team invented the nanoshells, they weren't initially sure what potential they held.

The first nanoshells made by Dr West are designed to absorb infra-red light.
ECONOMIST: Treating tumours
For the past few years, her work has focused on nanoshells -- miniscule spheres of glass wrapped in a layer of gold.
Make your nanoshells the right size, then, and they can pass through the capillary pores and lodge in a tumour, but not in a normal organ.
Halas worked with her Rice colleague, bioengineer Jennifer West, and they found that they could inject nanoshells into mice with cancer and get the particles to accumulate around the tumor.
The nanoshells have dramatic heating properties.
