Abstract

Hybrid virus/inorganic nanoscrystals are considered as important building blocks towards new types of functionality for electronic devices. We use tobacco mosaic viruses to assemble platinum nanoparticles and conjugate with quantum dots. By forming a thin hybrid nanocomposite layer in the crossbar junction, we show electronic memory effect based on electrical bistable states with a large on/off ratio, and long retention time. Such hybrid bio-inorganic nanostructures for the first time are promising for future bio-inspired nanoelectronics.
