Tetrahedral DNA nanostructure–gated solution-phase CRISPR/Cas12a system for probe immobilization-free, reagent-efficient, and dual-phase electrochemical detection of circulating microRNAs in liquid biopsy

Liquid-biopsy nucleic acid biomarkers hold strong promise for non-invasive cancer diagnostics, yet their ultralow abundance presents substantial analytical challenges. Conventional electrochemical biosensors rely on complex probe immobilization, whereas emerging homogeneous strat...
