Now, scientists from the CNRS and the University of Tokyo have developed the use of a novel enzyme-based technique, providing the initial clues as to how these technical obstacles may be overcome.These are the questions that research teams from the LIMMS (CNRS / University of Tokyo) and Gulliver (CNRS / ESPCI) laboratories have attempted to answer.Specifically, the researchers have made use of the reactions of three enzymes to design chemical “neurons” that reproduce the network architecture and ability for complex calculations exhibited by true neurons.The fruit of a decade of cooperation between French biochemists and Japanese microfluidics engineers, these breakthroughs may eventually permit better screening for certain diseases as well as the manipulation of gigantic DNA-encoded databases.By 2025, the total volume of digital data generated by humans is expected to reach 175 zettabytes.1 Since current storage media are relatively bulky, fragile, and energy-intensive, DNA may provide a viable alternative—able to contain all existing data within the space of a shoebox."
