CHICAGO – Surface-enhanced Raman spectroscopy (SERS) could help identify forged artworks. Researchers are using it to analyze paintings by 19th-century Mary Cassatt and the pastels she used to identify whether the materials were natural, synthetic or organic colorants. Determining the pastels’ chemical classes will help the scientists to distinguish between specific dyes, revealing the era in which a work of art was crated and perhaps whether it is authentic.


Richard Van Duyne, a chemistry professor at Northwestern University, and colleagues have accomplished the first direct extraction less and nonhydrolysis SERS study of delicate pieces of art.
