Green Synthesized Phytochemically (Zingiber officinale and Allium sativum) Reduced Nickel Oxide Nanoparticles Confirmed Bactericidal and Catalytic Potential

Abstract

Phyto-synthesized nanoparticles (NPs) having reduced chemical toxicity have been focused globally and become essential component of nanotechnology recently. We prepared green phytochemically (ginger and garlic) reduced NiO-NPs to replace synthetic bactericidal and catalytic agent in textile industry. NPs were characterized using ultraviolet visible spectroscopy (UV-Vis), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesis of NPs was confirmed by XRD and UV-Vis having strong absorption at 350 nm with size ranged between 16-52 nm for ginger and 11-59 nm for garlic. Scanning and transmission electron microscopy confirmed pleomorphism with cubic-and more spherical-shaped NPs. Moreover, exact quantities of garlic and ginger extracts (1:3.6 ml) incorporated to synthesize NiO-NPs have been successfully confirmed by FTIR. Phytochemically reduced NPs by garlic presented enhanced bactericidal activity against multiple drug-resistant Staphylococcus aureus at increasing concentrations (0.5, 1.0 mg/50 μl) and also degraded methylene blue (MB) dye efficiently. Conclusively, green synthesized NiO-NPs are impending activists to resolve drug resistance as well as environment friendly catalytic agent that may be opted at industrial scale.

Algal Magnetic Nickel Oxide Nanocatalyst in Accelerated Synthesis of Pyridopyrimidine Derivatives

“…Moreover, no sensible changes have been observed in peak position when the sample stored up to 6 months in the laboratory, indicating high stability of bioproduced NiO NPs in aqueous green media. Previous studies reported the optical absorption peak of biological NiO NPs in the range of 330-350 nm using green synthesis methods 17,18,30 which are in good agreement with our results.…”

“…Among these tremendous efforts, nickel oxide nanoparticles have been developed as an efficient catalyst in chemical synthesis of a wide range of valuable organic compounds such as spiro and condensed indole derivatives 11 , aromatic heterocycle 12 , 5-substituted 1htetrazoles 13 , quinolines 14 , and spirooxindoles 15 . There are a variety of green methods that have been addressed the construction of the nickel oxide nanoparticles (NiO NPs), mostly relied on plant-assisted bioreduction strategy [16][17][18] .…”

Photocatalytic, Bactericidal and Molecular Docking Analysis of Annealed Tin Oxide Nanostructures

“…Significant zones of inhibition recorded for SnO (250, 500 and 750 °C) samples for E. coli and S. aureus ranged Size, concentration and morphology of nanostructures directly affects oxidative stress produced. Antibacterial activity imperiling size and concentration portrays inverse relation to size [68][69][70]. Nanostructures more efficiently produce reactive oxygen species (ROS) which exist in bacterial membrane resulting cellular organelles extrusion and bacteria death [71].…”

Synthesis and characterization of microbial mediated cadmium oxide nanoparticles

“…Nanotechnology is a potential interdisciplinary science, has a broad range of promising utilization in biomedicine and biotechnology (Naz et al, 2018; Qamar, Asgher, Khalid, & Sadaf, 2019). It facilitates the field of biomedicine by using nanoparticles (NPs) through various physical and chemical processes (Aqeel et al, 2020; Haider et al, 2020a; Mansoor et al, 2017; Pourebrahim et al, 2018; Somasundaram, Rajan, Sangaiya, & Dilip, 2019). However, innovations toward sustainable and ecofriendly routes of synthesis are need of hour (Imran et al, 2018; Jeyaraj et al, 2013; Naz et al, 2017; Zangeneh, Zangeneh, & Moradi, 2020).…”
