- ... Here, we propose a new two-layer three-dimensional (3-D) DNA walker sensor with highly integrated entropy-driven and enzyme-powered reactions for the first time. The 3-D DNA walker sensor is constructed by assembling densely carboxyfluorescein-labeled single strand oligonucleotides (inner-layer tracks) and nucleic acid complex S (outer-layer tracks) on a microparticle. In the presence of the targe ...
