A simple electrochemical DNA biosensor based on a glassy carbon electrode (GCE) was prepared by adsorbing double-stranded DNA (dsDNA) onto the GCE surface and subsequently used for the detection of dsDNA damage induced by hydroxyl radicals. Investigation of the mutual interaction between hydroxyl radicals and dsDNA was conducted using a combination of several electrochemical detection techniques:...
New voltammetric DNA biosensor based on a microcrystalline natural graphite–polystyrene composite film in the role of a transducer was used for the investigation of the interaction between model carcinogenic substance (2-aminofluorene; one of the most extensively studied examples of the aromatic amine class of carcinogens) and calf thymus double-stranded DNA (dsDNA). The layer of dsDNA immobilized...
