The presence of biological contaminants in water like pesticides and hormones constitute a serious threat to the health and safety of human beings and their surrounding environment. We will show our recent advancement on the use of gold nanostructured surfaces for Surface enhanced Raman scattering devices applied to contaminant detection. The sensors reach good uniformity (better than $+/- 2$%) over 100 $\mum \times 100 \mu$. Moreover, we demonstrate limit of detection for pesticides like Thiram, and other pesticides on the order of 1 nM or about 1 ppb, well below the concentration limits allowed by the current regulation.
