Abstract
The aim of this study was to develop a simple electrochemical sensor for detection of (E.coli 25922) from water using gold nanoparticles. The water security and microbiological defense applications are globally concerns because of accuracy in the results and time saving technology. The traditional detection method of bacteria is requiring more time for the results. The biosensor reduce the detection time from 2 to 3 days to less than one hour with a simple identification method. The detection of pathogenic bacteria (E.coli 25922) is pivotal to public health for the water and food security. The electrochemical detection is applied for the detection of E. coli. However, in resulting the lowest bacterial concentration was weekly at 1 x 101 CFU/ml and the strongly on 1 x 106 CFU/ml. The electrochemical signal was increased with the increasing concentration of E. Cali. These results confirmed that the AuNPs-GCE is an effective approach to highly sensitive detection for the E.coli.
