Nano technology could be used to cure brain cancer

Titanium dioxide nano particles were used since they are sensitive to light, and the sensitivity used by the scientists to kill the cells. The new therapy works a bit like the Trojan horse.

The titanium dioxide nano particles are guided to the cancer cells by the antibodies which are able to selectively seek out the tumour cells. Once they find them, the scientists shine light on the cancerous cells. The light causes the titanium dioxide nano particles to release free oxygen radicals.
