摘要：
Dynamic light scattering was utilized to characterize bactericidal colloidal nanoparticles, food pathogen bacterial isolates in planktonic form. The method was proposed to study cultures of food pathogenic bacteria Staphylococcus aureus, Pseudomonas aeruginosa, Listeria monocytogenes, Escherichia coli, Salmonella and their interaction with nanoparticles. The zeta potentials of silver nanoparticles and bacteria were obtained using electrophoretic light scattering. Nanoparticles and bacteria were characterized by transmittance electron microscopy and the mechanism of antibacterial action was suggested.
