Application

  • MIL-101(Fe) based biomass as permeable reactive barrier applied to EK-PRB remediation of antimony contaminated soil.: The research utilizes EDTA as a chelating agent to enhance the performance of a MIL-101(Fe) based reactive barrier for the electrokinetic remediation of antimony-contaminated soil (Wang et al., 2023).

  • Proteomic signatures of synergistic interactions in antimicrobials.: This proteomics study investigates the synergistic interactions of antimicrobials, highlighting the role of EDTA in enhancing antimicrobial efficacy by disrupting microbial cell membranes (Zhou et al., 2023).

  • Rapid and zero-cost DNA extraction from soft-bodied insects for routine PCR-based applications.: This study presents a novel method for DNA extraction using EDTA, which simplifies and reduces the cost of DNA extraction from soft-bodied insects for PCR applications (Jangra and Ghosh, 2022).
