Nanofibers Perform Attoscale Chemistry

The chemical reactors allow experiments to be performed using just thousands of molecules.

By Katherine Bourzac

This illustration shows how the polymer nanofibers perform a reaction. The fibers are 200 nanometers in diameter and do not normally react with one another. However, when the fibers are exposed to a flash of heat (shown bottom), the polymers melt together, causing the formation of an “attoreactor,” where the two reactants meet each other.
