Binding-driven reactivity attenuation enables NMR identification of selective drug candidates for nucleic acid targets

Communications Chemistry, 2022
NMR spectroscopy could be a robust and reliable method for binding detection in drug discovery, but DNA/RNA targets remain challenging to analyze. Here, the authors explore the perturbation of the ligand reactivity caused by complex formation as a ...

Removing lead from water with carboxylate dendrimers and magnetic nanoparticles modified with carboxylate dendrimers

Applied Water Science, 2023
Contamination of water with heavy metals as lead (Pb2+) is a relevant problematic issue. In this work, we have tested different types of dendritic materials for lead removal from water and further recovery. The systems employed are magnetic nanoparticles
