Over the past decade, the development of nanomaterials has progressed rapidly toward their eventual use in products ranging from solar cells to medicines. However, tests of possible toxic effects of these substances on human health and the environment have been slow to get under way. Recently, an experiment raised concern about the soccer-ball-shaped carbon molecules commonly known as buckyballs. Now, other chemists confirm that finding and report an innovation that might disarm potentially toxic buckyballs.
