New device detects hazardous substances in water

A device for the rapid analysis of liquids on the content of hazardous substances - such as heavy metals - has been developed by researchers, who have used a method based on polymer optodes, very small plastic matrices that can be made sensitive to specific substances by means of special reagents. The matrices change color and their intensity depending on the concentration of the substance. The device is mobile, can carry out analysis in situ even at low temperatures, and its cost is many times less than the price of a spectrophotometer, the most used device for chemical analysis.
