Gold Nanoparticles Prevent Breast Cancer Cells from Migrating

Any breast cancer diagnosis instills fear, but it is metastatic breast cancer that threatens and takes women’s lives. Metastatic breast cancer is cancer that originated in the breast but has spread to other parts of the body. Diagnosing and treating breast cancer before it spreads is the clinical goal, but what if science could devise a way of immobilizing cancer cells? A team of researchers led by Mostafa El-Sayed, Professor of Chemistry and Biochemistry at  Georgia Tech’s School, has successfully cut off the foot-like protusions used by cancer cells to migrate, using gold nanoparticles.  While the goal in this experiment was to test the effectiveness of the gold nanoparticles in immobilizing breast cancer cells, the nanoparticles also seemed to kill cancer cells when heated.
