Arsenic Prototype 1
This is the beginnings of the Arsenic detector prototypes - Arsenic Prototype 1 within the full Chronology of the prototypes. This version was developed at EPFL in 2013, and is part of their 2013 Final Report.
For our first prototype, we decided to remain open to either Arsenic or E.Coli detection. We did background research on different methods, to have a panel of what was available and matched our criteria. We wanted to create a device open-source, not too expensive, easy-to-use and portable.
From all the methods we found, we chose fluorescence, which seemed to be the easiest technique to take out of the lab and allowed to detect both Arsenic and E.Coli.
