Detection of thiabendazole applied to organic fruit by near infrared surface-enhanced Raman spectroscopy

Csilla Müller, Leontin David, Simona Cintu Pînzaru

Thiabendazole (TBZ) is a chemical fungicide and parasiticide used to prevent mould, blight and other diseases resulting from long transportation and storage, largely used as an ingredient in waxes applied to the skins of citrus fruits. The authors describe their work using near infrared-surface-enhanced Raman spectroscopy and conventional Ag nanoparticles, which showed that TBZ was found both on organic fruit and at levels higher than regulations allow.

Surface-enhanced Raman scattering (SERS) spectroscopy identifies fraudulent uses of fuels

Peter White, Timothy Wilkinson

Fuels and the taxes raised from their sale are a big business around the world. To control smuggling, counterfeiting, theft and product diversion, markers can be placed in the fuel. The use of a SERS active compounds as markers is described as well as the development of a portable instrument for detection of the markers in the field.
