Interpretive Summary: Contamination of water with pesticide residues can be found throughout the year. Especially in developing countries, there is an urgent need to provide cost-effective tools for on-site screening and control. For this purpose a new sensor (AQUA-OPTOSENSOR) using monoclonal antibodies (mAbs) was developed for two pesticides, pyrethroids and DDT. This sensor consists of an instrument, controlled by a laptop computer, and a single-use chip. It measures emission of fluorescent light and the amount of light emitted is inversely proportional to the pesticide concentration in the sample. Using this technique, it will be possible to monitor pollution in water matrices without cost-intensive laboratory analysis. Advantages and limitations of this technology will be discussed.
