A novel carboxymethylcellulose-gelatin-titanium dioxide-superoxide dismutase biosensor; electrochemical properties of carboxymethylcellulose-gelatin-titanium dioxide-superoxide dismutase.

A novel highly sensitive electrochemical carboxymethylcellulose-gelatin-TiO(2)-superoxide dismutase biosensor for the determination of O(2)(•-) was developed. The biosensor exhibits high analytical performance with a wide linear range (1.5 nM to 2 mM), low detection limit (1.

Detection of superoxide radicals in tomato plants exposed to salinity, drought, cold and heavy metal stress using CMC-G-SOD biosensor.

A novel highly sensitive electrochemical carboxymethylcellulose-gelatin-superoxide dismutase biosensor was used for the determination of superoxide radicals enhancement in tomato plants exposed to salinity, drought, cold and heavy metal stress. The variations in superoxide radicals depending on abiotic stress was determined using biosensor. The superoxide radical production with regard to control rapidly was increased in tomato plants exposed to salinity, drought, cold and heavy metal stress.

Carboxymethylcellulose-gelatin-superoxidase dismutase electrode for amperometric superoxide radical sensing.

A novel, highly sensitive superoxide dismutase biosensor for the direct and simultaneous determination of superoxide radicals was developed by immobilization of superoxide dismutase within carboxymethylcellulose-gelatin on a Pt electrode surface. The parameters affecting the performance of the biosensor were investigated. The response of the CMC-G-SOD biosensor was proportional to O (2) (·-) concentration and the detection limit was 1.
