Abstract
Approaches to synthesis of Ag, Cu nanoparticles in liquid matrices and on the surface of both organic and inorganic powders and granules of different dispersity for biomedical purposes were analyzed. The advantages of nanoparticle synthesis by the methods of physical deposition in vacuum over the methods of chemical and hybrid synthesis are given. The high effectiveness and advantage of deposition from the evaporator with a directed vapour flow in vacuum are shown, compared to the classical crucible evaporation scheme. Optimal technological modes of deposition from the evaporator were established for achieving uniformity of the directed vapour flow. The dependence between the target temperature, efficiency of the evaporation scheme and evaporator to target distance was experimentally determined. 15 Ref., 1 Tables, 2 Figures.
Keywords: nanoparticles, electron beam evaporation and deposition, composites, dispersed systems, silver, copper, directed vapour flow, vacuum
