According to the first stage of the research:
1) review of the literature on the development of new "green" methods for obtaining solutions of nanoparticles of silver (Ag0) and copper (Cu0), stabilized with biogenic surfactants (bioPAR) for their use as antimicrobial drugs with a broad spectrum of action has been done;
2) there were synthesized a new environmentally friendly bioSAS surfactants of biogenic origin for their use as a multifunctional reagent for the synthesis and stabilization of colloidal solutions of nanoparticles of silver and copper;
3) there were synthesized the colloidal solutions of nanoparticles of silver (Ag0), copper (Cu0) and copper oxide (CuO), stabilized by the new ecologically safe bioSAS synthesized in item 2 and their structure was confirmed;
4) it was shown that the rhamnolipid biocomplex (RBC) is an effective stabilizer of metal nanoparticles, in particular copper oxide (CuONPs).
5) the stability of the synthesized colloidal solutions of nanoparticles of silver (Ag0) and copper oxide (CuO) stabilized by the new ecologically safe bioSAS synthesized in item 2 was investigated;
6) it was investigated the antimicrobial properties of the obtained concentrated sols of silver nanoparticles (Ag0);
7) the formation of Ag4 nanocluster by the reaction of reduction of Ag + by hydrazine was studied by the methods of quantum chemistry and the thermodynamic parameters of the elementary stages of the process were established.
