Smartphone Arsenic Detection
Calling Erin Brockovich

The WHO estimates that 57 million people are exposed to drinking water containing too much arsenic. Prolonged consumption is highly toxic and may increase the chance of cancers, cardiovascular problems and respiratory diseases. Here too, digital innovation is radically changing the situation in the field of health. Using an existing algorithm for the detection of skin cancer, the University of Cambridge has developed a smartphone programme capable of measuring the concentration of common pollutants, such as arsenic, in water. It is by visually detecting the fluorescence of nanocrystals (QDs fluorescence) that your smartphone is capable of finding this substance in water, even when this falls inside acceptable levels.
