Abstract

A design for a biochip memory device based on known materials and existing principles is presented. The fabrication of this memory system relies on the self-assembly of the nucleic acid junction system, which acts as the scaffolding for a molecular wire consisting of polyacetylene-like units. A molecular switch to control current is described which is based on the formation of a charge - transfer complex. A molecular-scale bit is presented which is based on oxidation - reduction potentials of metal atoms or clusters. The readable 'bit' which can be made of these components has a volume of 3×107 Å3 and should operate at electronic speeds over short distances.
