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 ultra-violet 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.
Highlights
Nanotechnology matter influence with at least one dimension size 1–100 nm that provides ability to engineer material by controlling their size [17]
The maximum absorbance in nickel oxide (NiO)-NPs was observed around 350 nm (1:3.6 ml) which increased with extracts concentration accompanied by blue shift
Root extract incorporation having phytochemical groups resulted in successful NiO-NP synthesis revealed by Fourier-transform infrared spectroscopy (FTIR)
Summary
Nanotechnology matter influence with at least one dimension size 1–100 nm that provides ability to engineer material by controlling their size [17]. Nickel (Ni) and nickel oxide (NiO) NPs have great importance due to their particular magnetic, catalytic, and electronic properties in energy technology, magnetism, biomedicines, and electronics [9, 26, 35]. NiO with a wide band gap of 3.6 to 4.0 eV and cubic lattice structure has potential due to p-type semiconductor. These NPs having high chemical stability, super capacitance properties, electron transfer capability, and electro catalysis are being used in biomedicines and photocatalytic, antiinflammatory, and antibacterial activities [8, 10, 11, 45]. The emergence of infectious maladies, especially antibiotic-resistant (MDR), has devastated public health worldwide. Both pathogenic Gram-positive (G +ve) and Gram-negative (G −ve) bacterial strains are among major public health threats
