| dc.description.abstract | A superoxide anion (O2•–) biosensor has been developed based on layer-by-layer assembled poly-(diallyldimethylammonium) (PDDA) and superoxide dismutase (SOD) on the L-cysteine (Cys) modified gold (Au) electrode. In 25 mM phosphate buffer solution (pH 7.2), the {SOD/PDDA}n/Cys/Au electrode shows a pair of well-defined and nearly reversible peak at ~ 84 mV vs SCE, confirming the direct electrochemistry of SOD. Based on the bifunctional enzymatic catalytic activities of SOD to the oxidation and reduction of O2•–, the developed {SOD/PDDA}5/Cys/Au electrode exhibits good analytical characteristics in the detection of O2•–, such as low detection limit, good stability, reproducibility, selectivity and particularly a wide linear range (0.5 ~ 546 mM). | en_US |
