基于DNA的存储是归档海量冷数据的一种替代解决方案。其未来发展旨在满足热数据存储的需求，后者需要快速随机访问和高效的数据修改。在此，我们提出了一种基于DNA折纸纳米结构的链式数据存储（DONLDS）系统，该系统实现了链表架构。该系统使用不同的DNA折纸形状作为节点，在二进制位置存储多种数据（英文字母、数字、中文字符），实现222.22 Gbit/cm²的存储密度。指针由纳米结构边缘的DNA链定义，用于建立数据位置。此外，可分离的DNA链作为指令，能够实现指针的动态链接以进行精确存储，以及其可逆分离以进行动态数据检索。DONLDS系统消除了对完整结构遍历的需求，支持并行数据存储，并支持数据插入和删除。这突显了其在管理复杂数据集方面的适应性和准确性。未来发展旨在满足热数据存储对数据修改的需求。在此，作者提出了一种基于DNA折纸纳米结构的链式数据存储系统，该系统使用不同的DNA折纸作为数据存储节点，支持并行存储，并支持数据插入/删除。
