✦ Synopsis

Ordering of cationic fullerene derivatives on a DNA template by phosphate/fullerene complexation provides a rapid route to organic materials several hundred nanometers in length (shown on the right). Hydrophobic interactions between the fullerene units lead to DNA supercoiling that can be relieved by adding a nonionic surfactant. The products are easily imaged by transmission electron microscopy without the need for heavy-metal staining.
