Kinetically grafting G-quadruplexes onto one-dimensional DNA nanostructures with precise positioning was realized in this study. The programs hold great promise for label-free and enzyme-free detection of various targets as a result of signal amplification from G-quadruplexes, and building DNA nanostructures as scaffolds due to the molecular recognition capacity of G-quadruplex aptamers.
本研究实现了动力学地将 G-四链体接枝到具有精确定位的一维 DNA 纳米结构上。由于 G-四链体的信号放大，以及 G-四链体适体的分子识别能力作为支架构建 DNA 纳米结构，这些方案有望实现各种目标的无标记和无酶检测。
