Synergistic cascade amplification by catalytic hairpin assembly and terminal deoxynucleotidyl transferase for ultrasensitive detection of microRNA-21.
The accurate early detection of miRNA-21 is crucial for effective cancer diagnosis and prognosis assessment. However, traditional amplification strategies are limited by spatial obstacles and have insufficient signal transmission efficiency at the electrode interface. In this study, we designed a highly sensitive elect...
