QUT researchers created a biosensor using engineered proteins to detect and extract rare earth elements, offering a potential solution to growing demand and environmental challenges.

QUT synthetic biologists have developed a prototype for an innovative biosensor capable of detecting rare earth elements, with the potential for modification to suit various other applications.

Lanthanides (Lns) are essential elements used in electronics, electric motors, and batteries. However, current extraction methods are costly, environmentally damaging, and unable to meet the growing demand.
