Rare Earth Metals in Smartphones Can Now Be Tracked

Extracting rare earths from the environment or from industrial samples, like waste water from mines or coal waste products, is generally very challenging and expensive.

Researchers have developed a new protein-based sensor that can detect lanthanides, the rare earth metals used in smartphones and other technologies, in a more efficient and cost-effective way.

The sensor changes its fluorescence when it binds to these metals, according to the study published online in the Journal of the American Chemical Society.

The protein undergoes a shape change when it binds to lanthanides, which is key for the sensor’s fluorescence to “turn on”, said the study.

“These elements are called rare earths, and they include chemical elements of atomic weight 57 to 71 on the periodic table,” Cotruvo added. Pixabay

To develop the sensor, the researchers from Pennsylvania State University in the US used a protein they recently described and subsequently used to explore the biology of bacteria that use lanthanides.

“Lanthanides are used in a variety of current technologies, including the screens and electronics of smartphones, batteries of electric cars, satellites, and lasers,” said Joseph Cotruvo, Assistant Professor at Penn State and senior author of the study.

Extracting rare earths from the environment or from industrial samples, like waste water from mines or coal waste products, is generally very challenging and expensive.

“We developed a protein-based sensor that can detect tiny amounts of lanthanides in a sample, letting us know if it’s worth investing resources to extract these important metals,” Cotruvo said. (IANS)
