Two DNA conjugates modified with ethylenediaminetetraacetic acid and 1,10-phenanthroline were prepared as a pair of split probes. They were designed to form a duplex with their auxiliary groups facing each other, providing a microenvironment to accommodate lanthanide ions. The luminescent signal was amplified by catalytic duplex formation based on an entropy-driven DNA circuit.

使用熵驱动的DNA回路催化形成发光镧系元素

制备了用乙二胺四乙酸和1,10-菲咯啉修饰的两个DNA偶联物，作为一对分离探针。它们被设计为形成一个双链体，其辅助基团彼此面对，从而提供了一个可容纳镧系元素离子的微环境。通过基于熵驱动的DNA电路的催化双链体形成来放大发光信号。
