Approaches to Chemical and Biochemical Information and Signal Processing

We outline models and approaches for error control required to prevent buildup of noise when ``gates'' and other ``network elements'' based on (bio)chemical reaction processes are utilized to realize stable, scalable networks for information and signal processing. We also survey challenges and possible future research. \\[4pt] [1] Control of Noise in Chemical and Biochemical Information Processing, V. Privman, Israel J.
