It was shown for the first time using a complex of physicochemical methods (dynamic and electrophoretic light scattering, nanoparticle tracking analysis, transmission electron and atomic force microscopy, conductometry, pH-metry) that in a temperature range of 25—60 °С (S)-lysine aqueous solutions (1•10 –17 —1•10 –2 mol L –1 ) are disperse systems, where the nature and parameters of the disperse phase change with dilution, which affects the nonmonotonic dependences of the specific conductivity and pH of the system. Nanoassociates hundreds of nanometers in size were found to contain ordered water structures that are responsible for the size and ζ-potential of the disperse phase in the aqueous systems and also participate in the formation of spatially organized systems on the support.
