Spanish scientists have developed a way to quantitatively measure the amount of iron in a solution using a colour changing material and photos taken on a smartphone.
Iron is present in almost every aspect of our lives but an excess, known as iron overload, can cause significant long term effects ranging from liver damage to arthritis as a result of iron deposition in organs or joints. As such, the amount of iron in a variety of environments needs to be carefully monitored.
