New sensor detects rare metals used in smartphones

A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of researchers from Penn State developed the sensor from a protein they recently described and subsequently used it to explore the biology of bacteria that use lanthanides. A study describing the sensor appears online in the Journal of the American Chemical Society.
