Herein, we report a novel Fe foil-guided, in situ etching strategy for the preparation of highly uniform Ag@AgX (X = Cl, Br) nanowires (NWs) and applied the photoelectric-responsive materials for sensitive photoelectrochemical (PEC) detection of leukemia DNA. The Ag@AgX NW formation process was discussed from the redox potential and K value. The fabricated PEC platform for sensing leukemia DNA showed good assay performance with a wide linear range (0.1 pM to 50 nM) and low detection limit of 0.033 pM. We envision that our Fe foil-guided synthetic method could be applied to synthesize more photoactive materials for sensitive PEC detections.
在此，我们报告了一种新颖的 Fe 箔引导的原位蚀刻策略，用于制备高度均匀的 Ag@AgX（X = Cl，Br）纳米线（NWs），并将光电响应材料应用于白血病 DNA 的灵敏光电化学（PEC）检测。从氧化还原电位和 K 值讨论了 Ag@AgX NW 的形成过程。构建的用于检测白血病 DNA 的 PEC 平台具有良好的分析性能，线性范围宽（0.1 pM 至 50 nM），检测限低至 0.033 pM。我们设想，我们的 Fe 箔引导的合成方法可用于合成更多的光活性材料，以实现灵敏的 PEC 检测。
