Abstract

original image

Difficult, but excellent surface-enhanced resonance Raman scattering (SERRS) provides a fast and accurate method for the detection of ultra-small traces of trinitrotoluene (TNT) under low laser power and in a short integration time. In their Full Paper on page 8789 ff., H. L. Liu, L. B. Yang, J. H. Liu et al. describe how cetylpyridinium chloride modified on Ag sols not only acts as the surface-seeking species to trap sulfite-sulfonated TNT, but also undergoes complexation with the sulfonated TNT, resulting in the appearance of two charge-transfer bands at 467 and 530 nm.
