Gold nanoparticles synthesis and biological activity estimation in vitro and in vivo
The aim of the work was the synthesis of gold nanoparticles (GNP) of different sizes and the estimation of their biological activity in vitro and in vivo. Materials and Methods: Water dispersions of gold nanoparticles of different sizes have been synthesized by Davis method and characterized by lase...
