Summary: A novel ligand, BCA, and its Co(II), Ni(II), Cu(II) complexes were synthesized and characterized. The ligand acted as a tridentate ligand and formed distorted octahedral geometry around the metal ion. The modified electrode, [Co(BCA)2]Cl2/GCE, showed excellent electrocatalytic ability for detecting glucose and H2O2, with a detection limit of 0.133 mu M and 0.0666 mu M, respectively. Furthermore, the ligand and its metal complexes were evaluated for their antibacterial, antifungal, antioxidant, and cytotoxic effects, as well as their binding efficiency to cancer receptors.
