Abstract
The dimensional characteristics of nanoparticles of N-mono- substituted amino acid derivatives of fullerene C60 (AAFDs) in aqueous colloidal solutions, determined by dynamic light scattering (DLS) and small-angle X-ray scattering (SAXS), were compared. The DLS data on the dimensional characteristics of fullerene C60 and AAFD nanoparticles, obtained at scattering angles of 90° and 173°, are close in values with a correlation coefficient of 0.89, and the SAXS data indicate that AAFDs form ordered structures in solution. Based on the results of DLS and the ability of fullerene and AAFDs to inhibit peroxyl radicals, it can be concluded that varying the concentrations of the studied compounds in the range from 10-7 to 10-3 m does not affect the degree of aggregation of their nanoparticles.
