Development of Nucleic‐Acid‐Based Electrochemical Biosensors for Clinical Applications

Nucleic acids are remarkable molecules. In addition to Watson-Crick base pairing, the different structural motifs of these molecules can bind non-nucleic acid targets or catalyze chemical reactions. Additionally, nucleic acids are easily modified with different molecules or functional groups. These properties make nucleic acids, particularly DNA, ideally suited for use in electrochemical biosensors, both as biorecognition elements and redox …
