Digital information processing in molecular systems

The information processing at the molecular level is possible and even relatively complex logic devices can be built on the basis of simple chemical systems. A combination of chemistry with Boolean logic and theory of information may lead to understanding of the molecular processes responsible for information processing in natural systems. Boolean analysis of various chemical systems including those involving genomes may lead to better understanding of nature. Additionally, chemical logic devices constitute a new platform for drug activation and delivery which limits the deleterious effects especially during anti-tumor therapy.
