The synthesis of nanocrystalline silver (nanosilver, NAg) was a major aim of this work. Nanosilver is a nanomaterial of great interest [1-3] due to its special biocidal properties, which are particularly desirable in various fields such as medicine, cosmetology, materials engineering, construction and others [4,5]. We aimed to develop a new method for the preparation of nanosilver, which would be completely environmentally friendly. This paper discusses the process of obtainingnanosilvervia chemical reduction. Silver nitrate (V) served as the source of silver ions, and glucose was responsible for the reduction. The stabilizing agent was a natural protein substance, gelatin, and was added to inhibit the growth of metallic agglomerates. The use of gelatin as a stabilizing factor and glucose as a reducing agent does not to interfere with the natural environment. The use of these substances renders this method environmentally friendly and is consistent with the principles of green chemistry. We investigated the influence of the independent variables, namely the molar ratio of the reducer to silver ions, the mass content of the stabilizer, the temperature and pH on the resulting suspension properties. Particle size was determined using dynamic light scattering, and a study carried out on the Zetasizer Nano-CI provided information on the electrokinetic potential, which reflects the stability of the colloidal system. Atomic force microscopy was used to image the obtained suspension.
