Implementation of a redox microarray: an experimental model for future nanoscale biomolecular computing using...

The possibility of constructing high-density parallel computing architectures using molecular electronics technology is explored. By employing molecular computing devices, new circuitsystem integration could be realised. To clarify the proposed concept, an experimental model of a redox microarray is presented. A first experimental system for a redox microarray consists of a two-dimensional array of platinum microelectrodes to catalyse reversible reactions of redox-active molecules. Experimental results of active wave propagation in the redox microarray are presented to demonstrate the potential of molecular computing devices for creating artificially programmable reaction-diffusion dynamics for specific target applications.
