Design Criteria

Having chosen to focus on Arsenic detection, the design criteria are more precise. We also try to not forget E.Coli detection which is linked to Coliform bacteria proportion. We want to create a device to detect Arsenic presence in water but that could also be adapted to E.Coli detection by means of some minor changes. We decide that our device has to present these criteria:


Fluorescence kit: We decided to use a bacteria expressing green fluorescent protein when put in presence of Arsenic as a sensor. It implies to find a way to measure the fluorescence and relate it to a quantity of Arsenic. Furthermore, E.Coli can also be detected by fluorescence (but with other wavelenght than GFP). To design a kit measuring fluorescence we need:
