Hairpin-Structured DNAzyme-Initiated Spherical Hybridization Chain Reaction Cascade Enables Highly Sensitive Electrochemical Detection of MicroRNA

Sensitive and accurate detection of low-abundance microRNAs (miRNAs) in complex biological matrices is critical for early disease diagnosis. Herein, we report a homogeneous cascade amplification-based electrochemical biosensing platform that integrates hairpin-structured DNAzyme-assisted target recycling amplification...

A dual-mode photoelectrochemical/ratiometric fluorescence sensing platform for dopamine detection based on a ternary MEG heterostructure.

Self-validated bioanalytical systems based on mechanistically orthogonal dual-mode transduction have attracted considerable interest, yet their development critically depends on multifunctional heterostructure materials that simultaneously enable efficient charge separation and well-resolved dual-emission output. Herei...
