Bistable switches are fundamental elements for information management and storage in electronic devices, such as for example memory sticks. Scientists first incorporated genetic switches into bacterial cells over a decade ago, but the capacity of those switches was limited to a few specific examples. Researchers from the Department of Biotechnology of the National Institute of Chemistry and from the Centre of excellence EN-FIST now succeeded in constructing genetic switches, which can, in principle, be designed in thousands of variations.
