Abstract- The goold nanoparticles show the strong surface Plasmon band in UV- Vis spectrum. The strong interaction is between gold nanoparticles and thiol compounds. In the presence of alkyl mercaptans, the Au NPs aggregate. Alkyl mercaptans cause a red shift and broadening of surface Plasmon band of AuNPs at 520 nm in UV-Vis spectrum. In this paper, we investigate the interaction of different alkyl mercaptans with Au NPs and found that Au NPs aggregation with alkyl mercaptan with shorter chain length is faster than the one with longer chain length. We report the simple and rapid detection method for alkyl mercaptans with different chain length using red shifts of surface plasmonic absorbance.
