Nano-sized materials are known to play important role in basic and applied sciences thus the metal and metal oxide nanoparticles have been intensively studied in the past decade [1,2]. The metal oxides particularly exhibit fascinating properties such as electronic, catalytic, magnetic and antimicrobial activity owing to their large surface area to volume ration due to a high fraction of atoms [3,4]. Zinc oxide nanoparticles have a wide band gap of 3.3 eV at room temperature and high excitation binding energy of 60 meV, which helps it to demonstrate outstanding catalytic, optical, photochemical and electronic properties [5,6]. Zinc oxide nanoparticles are known to possess unique UV filtering, antibacterial, antifungal properties also which leads to its extensive use in cosmetic and healthcare industries [7-9]. Previous studies suggest that the strong antibacterial activity of zinc oxide nanoparticles against a variety of pathogenic Gram-positive and Gram-negative bacteria attributed to its capacity of releasing Zn 2+ ion from ZnO complex and interruption of lipid bilayer integrity, ROS generation and subsequent damage to DNA and protein of the host cell [10,11]. Chemical and physical methods of nanoparticle synthesis have

Two novel dinuclear Zn(II) and tetranuclear Co(II) complexes of a tetradentate N2O2 Schiff base ligand (H2L = N,N′‐bis‐(4‐hydroxysalicylidene)‐1,3‐diaminopropane) were prepared. The structures of the H2L ligand, [4(Zn2L(μ‐O2CCH3)(O2CCH3)(H2O))]⋅4CH3OH⋅3H2O (complex 1) and [Co4L2(μ‐O2CCH3)2(O2CCH3)2]⋅2H2O (complex 2) were unambiguously characterized by elemental analysis, mass spectrometry, Fourier‐transform infrared spectroscopy (FT‐IR), 1H nuclear magnetic resonance (NMR), and UV–Vis spectroscopy. Single crystal X‐ray diffraction studies revealed that two Zn(II) nuclei of 1 were connected through μ‐phenolato and μ‐acetato bridges and had distorted square pyramidal and distorted octahedral coordination geometries. Four Co(II) nuclei of 2, on the contrary, showed a Co4O4 cubane‐like configuration in which Co(II) cations and O atoms were located at alternating corners of a distorted cube. Density functional theory studies at the B3LYP/6–31 G(d) level were carried out to gain an insight into the thermodynamic stability of the complexes. in vitro cytotoxicity of the ligand and the complexes were evaluated using the MTT assay against breast cancer MCF7 cells, melanoma cancer A375 cells, and prostate cancer PC3 cells as representative human cancer cell lines. Complex 1 showed a remarkable activity against A375 and PC3 cancer cell lines. In addition, 1 and 2 were used as precursors to produce zinc and cobalt oxide nanoparticles via pyrolysis technique. The resulting ZnO and Co3O4 nanoparticles were characterized using FT‐IR spectroscopy, UV–Vis diffuse reflectance spectroscopy, powder X‐ray diffraction, and field emission scanning electron microscopy. Then, these nanoparticles were used as heterogeneous catalysts in the oxidation of benzyl alcohol with hydrogen peroxide at room temperature. Both catalysts showed good recyclability with a negligible decrease in their efficiency during four catalytic cycles. The results of theoretical calculations showed that the most stable product was benzaldehyde, which is in good agreement with the obtained experimental results.

“…FTIR pattern of ZnONPs ranges from 450 to 4000 cm −1 that absorption frequency at 528 cm −1 and 3451, 1552, 2170, and 1399 cm −1 which correspond to the -OH, N-H, C=C, and C-H bond stretching which indicates the presence of a reduction of ZnONPs [13]. The FTIR spectrum of both chemical and biosynthesized Pithecellobium dulce and Lagenaria siceraria leaf extract showed strong absorption bands at 2848, 2854, and 2863 cm −1 which may be attributed to the stretching mode of C-H bonds and bonds at 1618, 1622, and 1643 cm −1 are attributed to C=C stretch and C=O vibration [14].…”

Objectives: The aim of the present study is a synthesis of zinc oxide nanoparticles (ZnONPs) by green and chemical method. The nanoparticles were tested for their antimicrobial, antibiofilm activity, biocompatibility, and hemolysis activity. Methods: We have synthesized ZnONPs both by green and chemical synthesis using the coprecipitation method. To understand the functional group, absorbance, crystalline nature, size, and shape of the synthesized particles, Fourier transform infrared (FTIR), ultraviolet–visible spectroscopy, X-ray diffraction, and scanning electron microscopy were done. Antibacterial activity was carried out using different bacterial strains. The cytotoxicity of synthesized nanoparticles was checked using MTT assay with Klebsiella pneumoniae. Antibiofilm activities of both synthesized nanoparticles were done using Staphylococcus aureus and to assess the toxicity of nanoparticles at the cellular level, hemolysis assay was performed. Results: The yield of nanoparticles in green synthesis was much higher when compared to chemical synthesis. Spectral results showed that the synthesized nanoparticles were ZnONPs. Antibacterial, antibiofilm, and hemolysis assay showed that green nanoparticles were more potent than chemical nanoparticles. Conclusion: Hence, green synthesis provides an advantage over chemical synthesis as it is cost effective, environmentally friendly, and easily scaled up for large-scale synthesis.
