Sažetak
There are numerous reports of antibacterial activity of the silver nanoparticles (AgNPs) produced by chemical methods [1, 2], but the laser ablation in liquid has been proven to be the most convenient technique for the production of nanoparticles free of chemical byproducts. Here we present the study of AgNPs and the influence these nanoparticles have on the bacteria and their growth kinetics. AgNPs were produced by laser ablation in water and characterized by different experimental methods. In the present literature, there are only few reports on attempts to model the bacterial growth in the presence of nanoparticles [3]. To explain the obtained growth curves of untreated and treated bacterial cells, we have designed the novel microscopic growth model described by three differential equations. Our model gives a good description of the experimentally obtained data.
