Enhancing Sensitivity in Nucleic Acid Detection via Collaborative Multiple Catalytic Cores in DNAzyme Nanomachines.

We introduce a multicore DNA nanomachine (MDNM), utilizing four binary DNAzymes for nucleic acid detection without the need for a preamplification step. This innovation remarkably yields a reduction in limit of detection (LOD), over 5-fold, as compared to single-core systems. This reduces the required test time thus highlighting the potential of MDNM in advancing nucleic acid detection.
