An electrochemical method was used to probe the interaction between 2-aminophenoxazine-3-one (AP) and the short DNA sequence related to the hepatitis B virus (HBV), and an electrochemical DNA biosensor was developed. The voltammetric signals of AP have been investigated at bare glassy carbon electrode (bare GCE), hybrid double-stranded DNA-modified GCE(More)
A novel hybridization indicator, bis(benzimidazole)cadmium(II) dinitrate (Cd(bzim)(2)(NO(3))(2)), was utilized to develop an electrochemical DNA biosensor for the detection of a short DNA sequence related to the hepatitis B virus (HBV). The sensor relies on the immobilization and hybridization of the 21-mer single-stranded oligonucleotide from the HBV long(More)
In this study, an electrochemical DNA biosensor was developed based on the recognition of target DNA by hybridization detection. The study was carried out using glassy carbon electrode (GCE) modified with lable-free 21-mer single-stranded oligonucleotides related to hepatitis B virus sequence via covalent immobilization and [Cu(dmp)(H(2)O)Cl(2)](More)
A novel label-free electrochemical DNA biosensor based on 4,4'-diaminoazobenzene (4,4'-DAAB) and multiwalled carbon nanotube (MWNT)-modified glassy carbon electrode (GCE) for short DNA sequences related to the hepatitis B virus (HBV) hybridization detection was presented. Differential pulse voltammetry (DPV) was used to investigate hybridization event. The(More)
