Exploration of Variable Solvent Directed Self-Healable Supramolecular M(II)-Metallogels (M = Co, Ni, Zn) of Azelaic Acid: Investigating Temperature-Dependent Ion Conductivity and Antibacterial Efficiency

“…In general, metal ions exhibit diverse antimicrobial activities, and these properties have been recognized throughout the history of medicine and healthcare. − In this study, the metallogels showed antimicrobial activity against both Gram-positive and Gram-negative bacteria . However, the effectiveness of antimicrobial activity varies between metallogels. , In the present work, it was found that Ni­(II)-metallogel showed slight antimicrobial efficiency compared to Co­(II)-metallogel and Zn­(II)-metallogel of azelaic acid used as the low molecular weight organic gelator. These differences in the antimicrobial activity of the metallogels could be due to the differences in the bioavailability of the metal ions during gel-formation.…”
