Metribuzin, which is a triazinone herbicide, is extensively used in agricultural activities in order to control the spread of broad leaved weeds and grasses. This herbicide is treated as a hazardous chemical, since it multiplies the contamination in the ecosystem by infiltrating to groundwater and soil layers. Thus, detection of Metribuzin in even low concentrations is of vital importance. To date, analytical methods such as High Performance Liquid Chromatography (HPLC), reversed-phase thin-layer chromatography (RP-TLC) with UV absorption detection, Gas chromatography, and Mass spectrometry were utilized in order to detect Metribuzin. At this point, Surface Enhanced Raman Spectroscopy (SERS), while being not as analytical as the methods discussed above, emerges as a significant alternative, since it requires almost no consumables, requires a very short time for analysis and it allows on site analysis. In this study Ag nanocubes were synthesized as a SERS substrate and They were utilized for detection of Metribuzin at concentrations from 10-3 to 10-10 M. Reproducibility, sensitivity and chemical stability tests exhibited that Ag nanocubes were excellent candidates of SERS substrates by allowing detection at ultra-low concentrations up to 10-10 M.
