Raman fingerprint for insecticide detection

Abstract:
Chinese scientists can detect trace concentrations of a hazardous insecticide using gold nanoparticles to boost its spectroscopic fingerprint.

Jin Wang and colleagues at the Chinese Academy of Sciences, Anhui, have demonstrated a fast, sensitive and practical approach for detecting methyl parathion. They synthesised gold nanoparticles and modified the surface with mono-6-thio-beta-cyclodextrin using the strong interaction between gold and sulphur. The cyclodextrin is well suited to bind the insecticide molecules and hold them in close proximity to the gold surface.
