Resumen:
Based on synthetic biology tools, a biosensor was designed to be specific for arsenic detection in water. It was designed to be cheap and easy to use (image based instructions will be enough). The device has a modular design which enables us to detect other water pollutants, with minor genetic modifications. In the presence of arsenic, the system develops a red color in a dose dependent manner that can be evaluated by naked eye and compared to an internal standard. Laboratory proof of concept worked nicely and the dynamic range of the assay (between 0 and 500 ppb) covers the critical arsenite concentrations according the World Health Organization. The current effort is focused on building a prototype that could be delivered for domestic use.
