“…Although plants naturally contain phytochemicals that act as reducing, stabilizing, and capping agents, different plants have different contents. This clearly shows that a strong scientific background study on the taxonomy of plants is needed to understand the principle and function of these phytochemicals in green synthesis [ 130 ]. From Table 1 , most of the studies have suggested that common active compounds, such as polyphenols and flavonoids, play crucial roles in green synthesis.…”

Plants are rich in phytoconstituent biomolecules that served as a good source of medicine. More recently, they have been employed in synthesizing metal/metal oxide nanoparticles (NPs) due to their capping and reducing properties. This green synthesis approach is environmentally friendly and allows the production of the desired NPs in different sizes and shapes by manipulating parameters during the synthesis process. The most commonly used metals and oxides are gold (Au), silver (Ag), and copper (Cu). Among these, Cu is a relatively low-cost metal that is more cost-effective than Au and Ag. In this review, we present an overview and current update of plant-mediated Cu/copper oxide (CuO) NPs, including their synthesis, medicinal applications, and mechanisms. Furthermore, the toxic effects of these NPs and their efficacy compared to commercial NPs are reviewed. This review provides an insight into the potential of developing plant-based Cu/CuO NPs as a therapeutic agent for various diseases in the future.

In recent years, the biosynthesized of metallic nanoparticles has been rapidly growing due to their environmentally synthesis and widespread applications in science and industry. In this study, we have reported the green synthesis of NiONPs using an aqueous extract of Trigonella subenervis (NiONPs@TS). The nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and energy-dispersive X-ray spectroscopy (EDS). To find various applications for NiONPs@TS, the nanoparticles (NPs) were used as a catalyst for synthesizing some benzimidazole derivatives. The electrochemical behavior and antibacterial activity of NiONPs@TS were also evaluated. FE-SEM images exhibited a uniform spherical morphology in size of 28.21 nm for the biosynthesized nanoparticles. According to the XRD analysis, 26.43 nm was measured for NiONPs@TS crystal size. Benzimidazole derivatives were synthesized using NiONPs@TS as the catalyst with a yield of 69-92%. NiONPs@TS showed a significant electrocatalytic activity to glucose oxidation. The linear response range and detection limit were found to be 10-200 and 3.2 μM, respectively. Furthermore, NiONPs@TS exhibited an acceptable antibacterial activity in various assays, including well diffusion, disk diffusion, minimum inhibition concentration (MIC), and minimum bactericidal concentration (MBC). The best antibacterial activity was obtained against Bacillus subtilis with MIC of 4.0 ± 0.0 μg/ml and MBC of 6.7 ± 2.3 μg/ml. The obtained results showed the ability of NiONPs@TS in different fields such as catalytic, electrochemical sensing, and antibacterial activity, which can be contributed to the presence of biomolecules in T. subenervis extract.

“…Bio-inspired methods for the synthesis of nanoparticles offer distinct advantages, because of the direct use of natural and biological resources through more simple, non-toxic biocompatible and inexpensive synthesis routes [33,34]. Among the bio-inspired methods, the green synthesis of metal oxide nanoparticles using plant extracts can be highlighted as a simple, economical, and eco-friendly method [35]. Plant extracts contain bioactive compounds such as phenols, ascorbic acid, flavonoids, polyphenolic, citric acid, alkaloids, terpenes, and reductase [36].…”

Green manufacturing of catalysts enables sustainable advanced oxidation processes and water treatment processes for removing trace contaminants such as pesticides. An environmentally friendly biosynthesis process produced high-surface-area CuO and NiO nanocatalysts using phytochemicals in the Capparis decidua leaf extract, which served as a reductant and influenced catalyst shape. Capparis decidua is a bushy shrub, widely distributed in dry and arid regions of Africa, Pakistan, India, Egypt, Jordan, Sudan, Saudi Arabia. The synthesized CuO and NiO nanoparticles were characterized by UV-vis spectroscopy (UV-vis), field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) and thermo-gravimetric analysis/differential thermal analysis (TGA/DTA). The produced nanoparticles were spherical and flower-like in shape and have a characteristic face-centered cubic structure of CuO and NiO. Biosynthesized catalysts were photoactive and degraded recalcitrant pesticide Lambda-cyhalothrin (L-CHT). Photocatalytic degradation of L-CHT was affected by the initial L-CHT concentration, solution pH levels between 5 and 9, and photocatalyst concentration. The L-CHT removal percentage attained by CuO photocatalyst (~99%) was higher than for NiO photocatalyst (~89%). The degradation of L-CHT follows a pseudo-first-order kinetic model, and the apparent rate constant (kapp) decreased from 0.033 min−1 for CuO to 0.0084 min−1 for NiO photocatalyst. The novel flower-shaped nanoparticles demonstrated high stability in water and recyclability for removing L-CHT pesticide contamination in water.
