Abstract
Two DNA conjugates modified with ferrocene and β-cyclodextrin were prepared as a pair of probes that work cooperatively for DNA sensing, in which the electrochemical signal of ferrocene on one probe was significantly "quenched" by the formation of an inclusion complex with β-cyclodextrin of the other probe on the DNA templates.
摘要
两种修饰有二茂铁和β-环糊精的 DNA 缀合物被制备成一对协同工作的 DNA 传感探针，其中一个探针上的二茂铁电化学信号通过与另一个探针在 DNA 模板上形成包合复合物而显著“猝灭”。
