The simplest disinfection model was proposed by Chick and Watson for for disinfection kinetics.
Several methods have been employed to synthesize silver nanoparticles among which, the chemicalreduction method has been extensively investigated because of its simplicity of performance and mild conditions .
In this study, the effect of phospholipid concentrations on the antibacterial and killing
kinetic of two Gram-positive and Gram-negative bacteria was studied and the Chick-Watson model was adopted for evaluation of AgNPs disinfection kinetics.
