Nanoparticle-Based Liquid-Liquid Extraction for the Determination of Metal Ions

Tyler Z. Sodia et al.

Summary: Traditional liquid phase extraction techniques are limited by excessive organic solvent use and multistep procedures, but a new nanoscale extraction approach using polymeric nanoparticles offers a one-step metal quantification assay. This rapid and efficient method allows for the accurate measurement of metals of interest without the drawbacks of larger-scale phase extraction approaches, with potential applications in biological research.
