GREEN SYNTHESIS OF Ag - Au NANOPARTICLES, ATTACHMENT ON THE SiO2 MICROSPHERE SURFACE

The basic principle of this study, a single particle bring together more than one material, it developed a variety of physical, chemical and biological properties to design particle systems show. Where in the core-shell particles were synthesized in four steps: In the first  stage metal insert ignore into journalissuearticles values(Ag, Au,); particles were produced using plant bioextracts. In a second stage, SiO 2 microspheres were prepared according to Stboer process. In the third stage, surface of silica  was modified In the final stage, the metal particles insert ignore into journalissuearticles values(Au, Ag); were immobilized   to the silica surface.
