[To a question on the impact of nanoparticles of metals present in the aquatic environment, on bacteria and continuous cell lines HEp-2 and BGM].

Promising application of nanoparticles and nanomaterials is the creation of sanitary hygienic means of new generation used for disinfection of water and indoor surfaces of mass use, furniture, sanitary technical equipment by virtue of modifying traditional materials to bring them effective biocidal properties, and for the development of methods in vitro for assessment their toxicity In this paper the possibility of the use various forms of silver, copper and aluminum as disinfectant for bacterial test organisms in the aquatic environment and assess their toxicity on biological models of continuous culture of BGM cells (a stable line of African green monkey kidney cells) and HEp-2 (Human epithelial type 2 (HEp-2) cells, derived from a human laryngeal carcinoma) is considered.
