Phytoremediation
PubMedPlants growing in contaminated or industrial soils could one day be harvested to recover rare-earth metals like dysprosium, reducing the need for destructive traditional mining that devastates landscapes.
Dysprosium is a rare metal that's essential for making the magnets inside electric cars and wind turbines, but mining it is environmentally damaging. Some plants can actually pull metals from the soil into their leaves and stems—a process called phytomining. This study created a quick, cheap light-based test that can screen thousands of plants to find which ones are best at soaking up dysprosium, making the idea of using plants as living metal harvesters much more practical.
Key Findings
The fluorescence assay can detect dysprosium at concentrations as low as 0.07 μM, with a detection limit of 0.2 μM even in complex plant tissue samples.
Sodium tungstate was incorporated into the method to improve accuracy when measuring dysprosium inside plant matrices.
The high-throughput design of the assay enables efficient screening of many plant species for their rare-earth accumulation potential.

Scientists developed a fast, sensitive fluorescence test to measure how much dysprosium—a rare-earth metal used in electric motors and wind turbines—plants absorb into their tissues, paving the way for using plants to mine this critical material from waste sources.
