Web10 apr. 2024 · These Ln-MOFs exhibit selective sensing of Fe3+ ions and Cr2O72− anions with better quenching constant values and lower detection limits. According to the tests, … WebHowever, Fe3+ was found to have higher affinity towards His(1,3) and His(2,4) binding pockets. Our results also suggest that Ni2+ exhibits the highest binding affinity towards His-tag6 over the other metal ions. Most of the structural variations of the His-tag6 motif were from the Histidyl side chains during metal ion binding.
