Voltammetric Detection of Damage to DNA by Arsenic Compounds at a DNA Biosensor
DNA biosensor can serve as a powerfull tool for simple in vitro tests of chemical toxicity. In this paper, damage to DNA attached to the surface of screen-printed carbon electrode by arsenic compounds in solution is described. Using the Co(III) complex with 1,10-phenanthroline, [Co(phen)3], as an electrochemical DNA marker and the Ru(II) complex with bipyridyne, [Ru(bipy)3], as a DNA oxidation ...
متن کاملVoltammetric Behavior of Nitroimidazoles at a DNA - Biosensor
The newly developed DNA-biosensor is a very promising tool for the investigation and study of the action of drugs specifically designed to interact with DNA. In this work the electrochemical reduction of nitroimidazole drugs was studied in the presence of DNA immobilized onto the surface of a glassy carbon electrode. This enabled preconcentration of the drug onto the electrode surface, which wa...
متن کاملVoltammetric behaviour of mitoxantrone at a DNA-biosensor.
The surface of an electrochemical glassy carbon electrode was modified with a layer of double-stranded DNA (dsDNA) or with double-stranded DNA conditioned in single-stranded DNA (ssDNA) and was used to investigate mitoxantrone-DNA interactions. Differential pulse and square wave voltammetry were applied to develop an electroanalytical procedure for the determination of mitoxantrone and evaluate...
متن کاملVoltammetric behavior of benznidazole at a DNA-electrochemical biosensor.
Benznidazole is a drug used commonly as a therapeutic agent against Chagas' disease in Brazil. To clarify the cytotoxic action of benznidazole the electrochemical reduction of benznidazole has been investigated using a DNA-electrochemical biosensor, prepared by modification of a glassy carbon electrode with DNA, and the results compared with reduction at a bare glassy carbon electrode. The depe...
متن کاملVoltammetric detection of damage to DNA caused by carcinogenic aminofluorenes using novel electrochemical DNA biosensors
The emissions of gasoline and diesel engines contribute significantly to ever increasing pollution of living environment. A specific part of exhaust gases is composed of carcinogenic derivatives of polycyclic aromatic hydrocarbons. Amino derivatives of parent hydrocarbon fluorene, namely 2-aminofluorene (2-AF) and 2,7-diaminofluorene (2,7-DAF), are well-known hazardous air and water pollutants ...
