Show affiliationsInterconnecting networks are fabricated by using calf-thymus DNA sodium salt and elementary DNA base adenine. Calf-thymus DNA sodium salt forms a complex wire-like network with poly(allylamine hydrochloride) which is a weak polyelectrolyte. The interconnection is formed by electrostatic forces during self-assembly. Adenine base and zinc oxide (ZnO) form a neural network, the conformation of which depends on the molar ratio of the two ingredients. Electrical measurements show that the formation of a calf-thymus and polyallylamine hydrochloride suprastructure may lead to a selective charge transfer network while the adenine-based network offers additional processing capability.
