Fabricating a nanostructure capable of reversibly patterning molecules is a fundamental goal within nanotechnology, underlying diverse processes such as information storage, scaffold-assisted assembly, and molecular transport. Here, we describe a DNA scaffold supporting a one-dimensional array of independently and reversibly addressable sites at 7 nm spacing. As a proof-of-concept, we demonstrate robust functioning of the device as rewritable memory. The bit state of each address is controlled by specific DNA strands with external readout provided by fluorescence measurements.
