Adsorption Studies of <i>Salmonella</i> Enteritidis and <i>Escherichia coli</i> on Chitosan-Coated Magnetic Nanoparticles.

ABSTRACT: One of the challenges of microbiological testing is the complex and lengthy sample preparation, causing delays in getting the final result. Immunomagnetic separation is one of the sample preparation techniques recently used to overcome this complexity. However, it is expensive, fragile, and requires cold storage. This study aimed to use chitosan-coated magnetic nanoparticles (cMNP) to capture bacterial cells from a simulated matrix and understand the interaction between the bacteria and the cMNP using batch adsorption studies. To illustrate the concept, Salmonella Enteritidis and Escherichia coli were used. Results showed that the adsorption of Salmonella Enteritidis and E. coli fitted the pseudo-second-order kinetic model (R² = 0.939 and 0.968, respe
