Carbon nanotube-based biosensors for DNA structure characterization

Autor: Albert A. Rizvanov, Timur I. Abdullin, I. I. Nikitina, Oksana V. Bondar

Publikováno v: Applied Biochemistry and Microbiology. 45:229-232

The possibility of DNA detection using electrodes modified with carbon nanotubes (CNTs) was studied. CNTs facilitate the electrochemical oxidation of DNA guanine nucleotide, which allows direct detection of DNA on a modified electrode. Electrochemica

Adsorption and oxidation of purine bases and their derivatives on electrodes modified with carbon nanotubes

Autor: Oksana V. Bondar, I. I. Nikitina, Timur I. Abdullin

Publikováno v: Russian Journal of Electrochemistry. 44:1345-1349

The electrochemical behavior of nitrogen bases and their derivatives is studied on electrodes modified with carbon nanotubes. On these electrodes, the strong adsorption of purines and their oxidation is observed at potentials in the vicinity of +0.8

Electrochemical properties of a two-component DNA-polyaniline film at the surface of glassy carbon electrode

Autor: Timur I. Abdullin, G. K. Budnikov, L. Z. Manapova, I. I. Nikitina, G. A. Evtugin

Publikováno v: Russian Journal of Electrochemistry. 43:1284-1288

Aniline electropolymerization on a DNA-modified glassy carbon electrode gives rise to a stable composite DNA-polyaniline film possessing redox activity over a wide range of pH values. The heights and potentials of the redox peaks linearly depend on p

Carbon nanotube-modified electrodes for electrochemical DNA-sensors

Autor: G. K. Budnikov, D. G. Ishmukhametova, O. A. Konovalova, M. Kh. Salakhov, Timur I. Abdullin, I. I. Nikitina

Publikováno v: Journal of Analytical Chemistry. 62:599-603

Glassy-carbon electrodes (GCEs) are modified with preoxidized multiwalled carbon nanotubes (CNTs). According to the data of atomic force microscopy, the layers of CNTs on GCEs possess a homogeneous nanostructurized surface. The voltammetric propertie

Detection of DNA depurination with the use of an electrode modified with carbon nanotubes

Autor: Oksana V. Bondar, Timur I. Abdullin, I. I. Nikitina

Publikováno v: Journal of Analytical Chemistry. 63:690-692

The possibility of detecting DNA depurination products on a glassy carbon electrode modified with carbon nanotubes (CNTs) was revealed. Adenine and a guanine DNA nucleotide were oxidized at similar potentials of about +1.1 V against Ag/AgCl; this fac
