Shown are living human cervical cancer cells containing mesoporous silica nanospheres capped with iron-oxide nanoparticles are drawn through solution toward a small rare-earth magnet placed beside the vial at Ames Lab. At Ames Lab, chemists has found a way to use nanoscale to deliver a dose of chemotherapy drugs to specific cancer cells without the risk of side affects to healthy cells. Using tiny silica parties called nanospheres to carry drugs inside living cells, the lab is studying different methods to control whether the particle delivers its pharmaceutical payload. The nanospheres are only about 200 nanometers in diameter, the size of the virus, so they would not trigger an immune response in the body. In addition, they can be readily absorbed by the cells. The nanospheres may provide the key to studying what takes place within a cell. For more information or additional images, please contact 202-586-5251.
