Making 13 from 55 : Au 55 nanoclusters that interact with the major groove of B‐DNA (see energy‐minimized structure), are broken down into Au 13 clusters by the transformation of B‐DNA into A‐DNA, during which the major groove shrinks dramatically. This transformation, which results in the formation of Au 13 wires, is initiated by the dehydration of the B‐DNA under the conditions required for electron microscopy.
