Investigators from Faculty of Sciences Report New Data on DNA Research (Development of a voltammetric procedure based on DNA interaction for sensitive monitoring of chrysoidine, a banned dye, in foods and textile effluents)

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on DNA Research are presented in a new report. According to news reporting from Rafsanjan, Iran, by NewsRx journalists, research stated, "Here, the interaction of chrysoidine (CSD) with a ds-DNA and its determination in foods and textile effluents was assessed. The interaction was studied by monitoring the change in the oxidation peaks of guanine, adenine and CSD using differential pulse voltammetry (DPV)."

The news correspondents obtained a quote from the research from the Faculty of Sciences, "In order to investigate the interaction of CSD with ds-DNA, a pencil graphite electrode (PGE) modified with multiwall carbon nanotubes (MWCNTs) and a ds-DNA was used. Poly( diallyldimethylammonium chloride), PDDA, was used to establish MWCNTs with PGE and with the ds-DNA. Electrochemical oxidation of CSD bonded on DNAIMWCNTs-PDDA/PGE and decreasing in the intensities of the oxidation signals of guanine and adenine (of the ds-DNA), after their interaction with CSD, were used to obtain the analytical signals. CSD could preconcentrate at DNA/MWCNTs-PDDA/PGE surface. The advantages of the proposed method are the extremely low detection limit (0.03 mu g mL(-1)), wide linear dynamic range (0.05-15.00 mu g mL(-1)), selectivity and cost effective for CSD determination."

According to the news reporters, the research concluded: "The capability of the biosensor was validated with analysis of CSD in fish, sauces and textile effluents."
