Researchers from the University of Burgos (Spain) have developed a smart material which changes colour based on the amount of iron in a fluid, whether it be water, wine or blood serum. Afterwards, if the result is photographed with a digital camera such as those on mobile phones, the concentration of this metal can be quantified without the need for chemical analysis.
