我们报告了使用带有 16 个 DNA 修饰电极的硅芯片(DME 芯片),利用 DNA 介导的电荷传输对 DNA 和 DNA 结合蛋白靶标进行多重检测。在具有四重冗余的单个 DME 芯片上同时区分四个 DNA 序列,其中包括一个包含单碱基错配的序列。这些芯片还能够研究限制性内切酶 Alu1 的序列特异性活性。 DME 芯片支持高重复性的致密 DNA 单层形成,与市售棒电极的统计比较证实了这一点。芯片上的工作电极区域直径减小至 10 µm,揭示了有利于高灵敏度和快速动力学分析的微电极行为。这些结果说明了 DME 芯片如何以稳健且内部标准化的多重格式促进 DNA 和 DNA 结合蛋白靶标的灵敏和选择性检测。
We report the use of silicon chips with 16 DNA-modified electrodes (DME chips) utilizing DNA-mediated charge transport for multiplexed detection of DNA and DNA-binding protein targets. Four DNA sequences were simultaneously distinguished on a single DME chip with fourfold redundancy, including one incorporating a single base mismatch. These chips also enabled investigation of the sequence-specific activity of the restriction enzyme Alu1. DME chips supported dense DNA monolayer formation with high reproducibility, as confirmed by statistical comparison to commercially available rod electrodes. The working electrode areas on the chips were reduced to 10 µm in diameter, revealing microelectrode behavior that is beneficial for high sensitivity and rapid kinetic analysis. These results illustrate how DME chips facilitate sensitive and selective detection of DNA and DNA-binding protein targets in a robust and internally standardized multiplexed format.
