This work presents a comprehensive study on DNA-based LFAs that completely avoids the use of proteins or pretreatment buffer. We address key fundamental challenges including optimizing buffer conditions for effective DNA immobilization on paper, understanding sequence-dependent detection, and ultimately developing patterning techniques that allow DNA patterns to appear on paper that exhibit distinct shapes depending on the introduced input sequences.
这项工作对基于DNA的侧向流动分析装置进行了全面研究，完全避免了使用蛋白质或预处理缓冲液。我们解决了关键的基础挑战，包括优化缓冲条件以实现DNA在纸上的有效固定、理解序列依赖性检测，并最终开发出图案化技术，使DNA图案能出现在纸上，这些图案根据引入的输入序列呈现出不同的形状。
