Development of an electrochemical DNA biosensor, using a gold electrode modified with a self-assembled monolayer composed of a peptide nucleic acid (PNA) probe and 6-mercapto-1-hexanol, is described. The sensor relies on covalent attachment of the 14-mer PNA probe related to the hepatitis C virus
Development of an electrochemical DNA biosensor for the direct detection and discrimination of double-stranded oligonucleotide (dsDNA) corresponding to hepatitis C virus genotype 3a, without its denaturation, using a gold electrode is described. The electrochemical DNA sensor relies on the
Development of an electrochemical DNA biosensor for direct detection and discrimination of double-stranded plasmid (ds-Pl) without the need for denaturation of the target plasmid sample using a peptide nucleic acid (PNA) oligomer as the probe is described. This goal was achieved by modification of
