Protein-Based Rare Earth Recovery via Condensation from scientists at Los Alamos National Laboratory offers a cleaner, flexible way to capture and concentrate rare earth elements from complex liquid mixtures by using a bio-inspired protein system that gathers target metals into separable clusters. The approach is designed to reduce reliance on harsher processing methods while supporting more resilient supply chains for critical materials used across energy, electronics, transportation and advanced manufacturing markets. Because the system is genetically modular, the same platform may be adapted with different Lanmodulin-type metal-binding variants to support selective capture needs across varied feedstocks. How it Works The technology modifies Lanmodulin, a protein known for strong rare earth element binding, by adding an “encapsulation peptide" to the N-terminus of the protein. Once the engineered protein binds rare earth elements in solution, the resulting protein-metal complexes can be triggered for self-assemble into biomolecular condensates, which are larger clusters that can be removed from the liquid. The material can then be separated and concentrated through various means–such as centrifugation, filtration, and sedimentation–reducing the need for immobilizing the protein on a column or other fixed support. Technical Description Rare earth elements are important to modern technologies; yet, processing and purification can be difficult and environmentally damaging. Pro
