Various types of carbon-based nanomaterials, such as buckyballs and nanotubes, have shown promise as drug delivery tools and imaging agents, but reports of toxicity associated with some of these materials have raised questions about their ultimate utility in clinical oncology. Three recent reports in the literature provide new insights into why certain carbon-based nanomaterials are toxic to cells and others are not.
