Enzymatic Synthesis of Redox‐Labeled RNA and Dual‐Potential Detection at DNA‐Modified Electrodes

Abstract

Ferrocene and anthraquinone were used to label RNA (red, dark blue), which could then be detected at an electrode surface bearing complementary DNA oligonucleotide probes (light blue). This approach is an electrochemical analog of popular fluorescence methods for gene expression analysis.
