Rapid data growth highlights the increasing demand for high-density storage solutions. Multiplexed optical recording based on synthetic inorganic nanoparticles represents the next generation of data storage. However, diverse photophysical properties of nanoparticles reduce their reliability and information density. Here, we present a highly programmable polychromatic DNA tetrahedral framework (PDTF) that enables precise control over their optical performances. By programming the size of PDTFs, we reduce the feature size of the recording medium to 3.4 nm, which was 41-fold smaller than that of commercially available Blu-ray technology. PDTF chains with up to 47 million distinct color codes further enhance optical storage with higher information capacity. Additionally, nanopatterning technology integrates the PDTFs into on-chip architectures, achieving an impressive density of 25.9 Gb/cm2. Finally, the PDTFs demonstrate excellent re-writability and long-term stability (10,826 years at room temperature), exhibiting promising potential in high-density and secure data storage applications.

使用多色 DNA 框架进行大规模多路复用光学记录


数据的快速增长凸显了对高密度存储解决方案日益增长的需求。基于合成无机纳米颗粒的多路复用光学记录代表了下一代数据存储。然而，纳米颗粒的不同光物理特性降低了它们的可靠性和信息密度。在这里，我们提出了一个高度可编程的多色 DNA 四面体框架 （PDTF），可以精确控制它们的光学性能。通过对 PDTF 的尺寸进行编程，我们将记录介质的特征尺寸减小到 3.4 nm，这比市售的蓝光技术小 41 倍。具有多达 4700 万个不同颜色代码的 PDTF 链以更高的信息容量进一步增强了光存储。此外，纳米图案化技术将 PDTF 集成到片上架构中，实现了令人印象深刻的 25.9 Gb/cm2 密度。最后，PDTF 表现出优异的可重写性和长期稳定性（室温下 10,826 年），在高密度和安全数据存储应用中显示出广阔的潜力。
