Abstract
Elements analysis, UV-Vis, FT-IR, and cyclic voltammetry have been used to characterize a new Iron (II), Zinc (II), and Cobalt (II) complex [Fe(II), Zn(II), Co(II)] complexes that contain 2,2'-bipyridine and pyrazine-2-carboxylic acid ligand. The interaction of this Fe (II), Zn (II), and Co (II) complex with calf thymus DNA techniques employed in fluorescence spectroscopy was investigated by UV-visible absorption. UV-Vis absorption studies yielded intrinsic binding constants (Kb) for the complex with CT-DNA of 1.9 x 104 and 2.1 x 104M− 1. Pseudomonas aeruginosa, Staphylococcus aureus, and Bacilli cereus pathogens were assessed for their antibacterial effectiveness against a range of microorganisms using nanosystems to determine the ligand and complex antibacterial activity.
