Gold Nano particles to improve the effectiveness of radiation therapy

A transmission electron micrograph of a breast cancer cell that has taken up gold Nano particles.

Gold Nano particles (AuNP’s) are used by postgraduates from the University of the Western Cape in radiation biology studies performed at iThemba LABS. These small particles enhance the radiation dose absorbed by cancer cells. To date the interaction with AuNP’s and X-rays has been noted that result in more radiation damage compared to cells irradiated without AuNP’s. Currently studies are conducted to test the influence of AuNP’s in cells treated with protons and neutrons.
