Plasmonic circular dichroism using Au fine particles and riboflavin

摘要: We report circular dichroism (CD) induced in the visible region using a composite film containing Au fine parti-cles and riboflavin. It is revealed that binding of chiral molecules to surface particles not necessary for plasmon-induced CD. Moreover, we find films dye glucose instead riboflavin induces CD signal at wavelength, where shows an absorption peak. The polarity reversed by enantiomer glucose.
