Abstract

original image

The image shows the developing biocompatible molecules with controllable, accurate, and reproducible molecular motor functions for mobile nanodevices. Seon Jeong Kim and co-workers show on page 1907 that the attachment of fullerene moieties to a single-strand DNA significantly improves the molecular switching and stability of this pH driven enthalpic molecular machine. Hydrophobic interactions between the terminal fullerenes in the folded i-motif conformation increased the machines power stroke and force generated.
