Abstract

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.
