Abstract The methods for the synthesis of gold sols in chloroform have been developed. The efficiency of gold organic sol for studying real objects of painting and its advantage over traditional hydrosol was demonstrated. A new practical application of gold organosols is proposed—the use for analysis of paintings by surface‐enhanced Raman scattering that can help to identify the dyes and hydrophobic binders in one probe. In practice, the application of metallic organosols makes possible to substantially simplify the procedure for sample preparation. It was also shown that the intensity of the surface‐enhanced Raman spectroscopy bands and the signal‐to‐noise ratios is improved with organosols in comparison with hydrosol. These results can contribute in the long term to the development of nondestructive approach to the analysis of works of painting.
