520		3	_aA novel hydrazinyl Schiff base ligand derived from 1-hydrazinylphthalazine and 1-(2H- benzo[d][1,2,3]triazol-2-yl)propan-2-one was synthesized and used to prepare metal complexes with Co(II), Pd(II), and Cd(II). The Schiff base ligand and its complexes were comprehensively characterized using various spectroscopic and analytical techniques, including conductometry, elemental analysis, FT-IR, UV-Vis, 1H NMR, 13C NMR, TGA, and mass spectrometry. The metal complexes exhibited enhanced antimicrobial and anticancer activities compared to the free Schiff base ligand. The Co(II) and Cd(II) complexes were transformed into nanostructures for environmental applications. These nanostructure complexes were characterized using XRD, SEM, AFM, Zeta Potential, DLS, Contact Angle measurement, and BET surface area analysis. Nanostructured forms of the Co(II) and Cd(II) complexes were developed and applied as quartz crystal microbalance (QCM) sensors for the detection of arsenic and cadmium ions in aqueous media, respectively. The nanosensors demonstrated high sensitivity, with detection limits as low as 0.1 ppm for cadmium and 1 ppm for arsenic. The effects of pH, temperature, and analyte concentration on sensor performance were investigated. The nanoparticles demonstrated excellent colloidal stability, high surface area, and favorable hydrophobic properties. Cytotoxicity studies confirmed their biocompatibility. Molecular docking studies provided insights into the compounds' binding interactions with various biological targets. This research highlights the versatility of the novel Schiff base [(E)-1-(2-(1-(2H-benzo[d][1,2,3]triazol-2-yl)propan-2- ylidene)hydrazinyl)phthalazine] and its metal complexes for environmental monitoring and potential biomedical applications. The extensive experimental characterization, theoretical computations, and practical applications in environmental and biomedical fields lead to a comprehensive understanding of these new compounds. The findings open up opportunities for further exploration in areas such as environmental remediation, water quality monitoring, drug development, and biosensing technologies. There is a particular emphasis on the role of specific Metal-Schiff base combinations in modulating the properties and applications of these complexes.
