Description
Likang Chu, Liqi Wan, Haixia Wang, and a wider team wrote this research paper, published in 2025. It builds a data storage and encryption system out of DNA droplets with a core and shell, using DNA's own programmability to run the needed operations.
DNA stores vast data in tiny space and sips energy, but writing, editing, and locking the data are hard. The team's layered droplets support encoding, erasing, rewriting, copying, and repair of stored information, all while staying easy to read. On top, computing circuits built from biomolecules add encryption tricks: multi-level logic locks, locks that change with time, locks driven by living systems, and fine-grained access control. The authors call it a step toward molecular storage that is both editable and secure, and that can grow to larger scales.
