Its aim is to design new devices for massive data storage on molecular media (PEPR MoleculArXiv). The PhD student will be hosted in the GenScale team at IRISA in Rennes and will collaborate with LIMMS, the CNRS international laboratory based in Tokyo. CONTEXT. The global production of digital data is growing exponentially, posing a significant challenge to available storage capacities. Despite advances in density and cost per gigabyte, conventional storage media face limitations in terms of energy efficiency, sustainability, cost, and environmental impact. In this context, digital data storage in DNA emerges as a promising technology, particularly for long-term archiving. DNA offers an extremely high theoretical information density, on the order of 10¹⁸ bits per mm³, as well as excellent stability when stored under appropriate conditions. These properties could enable the storage of large amounts of data in a compact and durable form, with limited maintenance and energy requirements during the preservation phase. A DNA-based storage system relies on a series of steps: (1) encoding digital data into nucleotide sequences, (2) synthesizing or constructing DNA molecules corresponding to data writing, (3) preserving the molecules, (4) retrieving the molecules containing
