Abstract:
Foods are the potent transmitting agent of more than 250 known diseases. Many researches has focused on the development of rapid and reliable biological sensors for the detection of pathogens. The main objective of this study was to develop disposable biosensor to detect Salmonella Newport extract based on polymer electrodes. Salmonella is a gram-negative, facultative intra-cellular bacterium which may penetrate ocular, nasal, oral or intestinal mucous membranes. Salmonella Newport causes significant clinical disease in livestock, particularly cattle, in humans, and in other animal species. Of 58 serotypes isolated by culture from culled dairy cows in five regional market cow establishments in the U.S., S. Newport was among the 30 most prevalent serotypes. The formed polymer electrodes exhibit high conductivity and have a diverse range of potential applications from sensor devices through to fuel cells. This study aimed to make a biosensor for the detection of Salmonella Newport extract. The polycarbonate was polymerized on the surface of fine polycarbonate or cellulose acetate membrane. The biosensor made under optimized conditions allowed the detection of 103 dilutions of Salmonella Newport extract
