摘要： DNA has emerged as an appealing material for information storage due to its great storage density and durability. Random reading and rewriting are essential tasks for practical large-scale data storage. However, they are currently difficult to implement simultaneously in a single DNA-based storage system, strongly limiting their practicability. Here, a Cell Disk storage system is presented, achieving high-density in vivo DNA data storage that enables both random reading and rewriting. In this system, each yeast cell is used as a chamber to store information, similar to a disk block but with the ability to self-replicate. Specifically, each genome of yeast cell has a customized CRISPR/Cas9-based lock-and-key module inserted, which allows selective retrieval, erasure, or rewriting of the targeted cell block from a pool of cells (disk). Additionally, a codec algorithm with lossless compression ability is developed to improve the information density of each cell block. As a proof of concept, target-specific reading and rewriting of the compressed data from a mimic cell disk comprising up to 105 blocks are demonstrated and achieve high specificity and reliability. The Cell Disk system described here concurrently supports random reading and rewriting, and it should have great scalability for practical data storage use. A novel Cell Disk DNA storage system, which engineers yeast cells as addressable chambers to store high-density DNA-encoded information, concurrently supports random reading and rewriting, making it promising for a variety of large-scale data storage applications. image
