The paper proposes an environmentally safe method for the synthesis of silver nanoparticles (Ag nanoparticles) using L-lysine as a reducing agent and stabilizer. using L-lysine as a reducing agent and stabilizer. It was investigated The influence of silver ion concentration (0.0015-0.003 mol/L) on the size, monodispersity and morphology of particles. It was found that L-lysine forms spherical nanoparticles of average size 12±2 nm with high stability of colloidal solutions. SAXS analysis confirmed the monodispersity, and atomic force microscopy revealed a lognormal radius distribution. The antifungal activity of synthesized Ag NPs against the mold fungi Aspergillus terreus, the efficiency of the fungicidal action is 94.4 %. The results demonstrate the role of L-lysine in the control of particle morphology and promising application of Ag NPs.
