Electrochemical Biosensor for Multiplexed Detection of Nucleic Acids Using a DNA Three-Way Junction with Metal Ion Intercalation

anopatterns is employed as an electrode. As targets of this biosensor, human papillomavirus type 16 and 18 DNAs are detected for validation of multiplexed target detection. We expect that this biosensor can be used for the multiplexed detection of various nucleic acid biomarkers, including viral DNAs.
