Fullerene Attachment Enhances Performance of a DNA Nanomachine

Fullerene moieties are attached to single-strand DNA and the pH-induced conformational changes are evaluated in detail. It is found that fullerene attachments significantly enhance the machine performance of the DNA strand by stabilization of internal structure through intramolecular hydrophobic interactions.S. R.
