Buckyballs May Threaten DNA

By Anonymous

The nanomaterials known as buckyballs could deform DNA molecules, interfering with biological functions, warns a team of chemical engineers conducting molecular dynamics simulations at Vanderbilt University. The studies found that, when buckyballs are dissolved in water, the soccer-ball-shaped materials would bind to the spirals in DNA molecules. Further study is needed to determine the possibility of long-term damage if large amounts of buckyballs are released into the environment or ingested by living organisms, according to the researchers.
