Abstract
A wide range of characteristics and properties of new materials for medicine (dimensional characteristics and phase composition of nanoparticles, and the possibility of preparing and stabilizing the colloidal systems) was studied. Stable aqueous colloidal systems with silver and copper nanoparticles were prepared. The source of copper and silver nanoparticles was porous condensates of the NaCl–Ag and NaCl–Cu composition, obtained by electron beam evaporation and condensation in vacuum. The stabilizers of colloidal systems were the surfactants, namely albumin, polysaccharides, and polyvinyl alcohol. Particle size distribution in colloidal systems was determined, using the dynamic light scattering method. Ref. 24, Tabl. 3, Fig. 8.
Keywords: electron beam physical vacuum deposition (EB-PVD); nanoparticles; silver; copper; surface-active substance; dynamic light scattering; colloidal system
