Figure 7. Images of mice before and after photothermal therapy (PTT) with gold nanostars (GNS).

The images were taken 3 days after injection with the gold nanomaterial. In the images above, the control group was injected with saline solution. Remission of the tumour in the mice treated with gold nanostars was observed while control mice displayed continued rapid tumour growth. Adapted from reference [12] and reproduced with permission.
