METAL NANOPARTICLES IN WATER PLANT EXTRACTS: METHOD OF OBTAINING AND STRUCTURE
This article presents a two-stage method for producing metal nanoparticles in aqueous extracts from plant raw materials. The method consists in the physical precipitation of discrete metal coatings onto the surface of plant objects using the Electron Beam Physical Vapor Deposition (EB-PVD) technology and the subsequent extraction of these combinations into the volume of deionized water. The shape and structure were studied: the average particle size, as well as the range of the size distribution of the obtained metal nanoparticles by laser correlation spectroscopy (LKS), scanning electron microscopy (SEM). Examples of laboratory and industrial equipment EB-PVD for the synthesis of nanoscale structures on the surface of plant objects are also given.
