Abstract

A review of modern concepts of nanoobjects is carried out. Various aspects of the properties of nanosized particles and promising possibilities of using nanomaterials in many fields of science and technology are considered. It is shown that nanoobjects have unusual physical and chemical properties, as well as features of biological action, which differs from the properties of the same substance in a continuous phase. In the nanosized state, the specific surface area and chemical potential of substances at the interface increase. It is noted that much attention is paid to the functional activity of silver nanoparticles in terms of imparting both bactericidal and bacteriostatic properties to various materials and products. The use of silver in the form of nanoparticles makes it possible to reduce the concentration of silver by a factor of hundreds, while retaining all its bactericidal properties. Silver nanoparticles are used as a biocidal additive — in the form of a modifier, intended for the creation and production of new materials, coatings and other types of products with biocidal properties of a wide spectrum of action. The choice of silver nanocomposites for impregnating textiles is due to their significant and indisputable advantages over all existing antimicrobial agents, since silver compounds, having a wide spectrum of antimicrobial activity, are largely devoid of the disadvantages associated with the problem of resistance of pathogenic microorganisms to them.
