MicroRNA-141 (miRNA-141) is of great significance in the early diagnosis and treatment of related cancers. Here, a biosensor was developed for detection of miRNA-141. Firstly, bio-metal organic framework (bio-MOF) with a certain porosity and good biocompatibility was synthesized. The bio-MOF could encapsulate a large number of methylene blue (MB) via ion-exchange process and maintain the biological activity of MB. Secondly, as one of the target recycling signal amplification technologies, catalyzed hairpin assembly (CHA) could assist the target miRNA-141 cycle to achieve signal amplification and further improve the biosensor sensitivity. As a result, the proposed ECL biosensor exhibited good sensitivity for microRNA-141 detection in a linear range from 1.0×10-16 mol/L to 1.0×10-6 mol/L with a limit of detection (LOD) of 3.3×10-17 mol/L (S/N=3). The spiked recoveries ranged from 99.9% to 102.0% (RSD ≤ 2.1%). The biosensor showed good stability and selectivity, wide linear range and high sensitivity, and opened up a new avenue for highly sensitive detection of various miRNAs.
