Three plants extracts were used for biosynthesis of Ag nanoparticles (AgNPs). AgNPs nucleation process requires effective reduction agents which secure Ag+ to Ag0 reduction and also stabilizing/capping agents. The UV-vis and TEM observation revealed that the best results were obtained by R. officinalis leaf extract. The strong SPR band peak appeared at the wavelength 418 nm. Synthetized AgNPs were globular, fine (~20 nm), uniform and stabile throughout the experiment. A rapid rate of AgNPs synthesis was also significant and economically advantageous factor. Fine (10-20 nm) and globular nanoparticles were synthetized also by U. dioica leaf extract, but the stability of nanoparticles was not permanent. Despite V. vitis-idaea fruit extract contains a lot of reducing agents, UV-vis did not confirm the presence of AgNPs in solution. Synthetized Ag particles were very unstable, Ag particles agglomerated very fast and clearly indicated sediment was formed.

François Chapeville (Franciszek Chrapkiewicz), an outstanding Polish biochemist, spent his entire adult life in France. After graduating in veterinary and biochemistry there, he completed a postdoctoral fellowship at the Fritz Lipmann laboratory at Rockefeller University in New York. There, he conducted studies that proved that the genetic information encoded in DNA is deciphered in the process of protein biosynthesis via adapter tRNA molecules (adapter hypothesis). In the years 1979–1991 he was appointed director of Jacques Monod Institute of Molecular Biology at the University VII in Paris. He was a great promoter of Polish-French cooperation in the natural sciences. He passed away in Paris at the age of 96. He was buried in his hometown of Strzyżów in the Podkarpacie region.
