“…The plant-mediated green syntheses of NPs is a facile, rapid, reliable, cost-effective, eco-friendly and one-step method, and, have a considerable benefit over microbial synthesis due to prolonged process of microbial isolation and their pure culture maintenance. Some earlier reports have also recommended green synthesis approach for copper and copper oxide NPs using Syzygium aromaticum bud extract [25], Ziziphus spina-christi fruit extract [26], Azadirachta indica leaf extract [27], Henna leaf extract [28], and Tragacanth gel [29].Azo dyes are synthetic colouring agents being utilized in a wide range of paper, plastic, tannery, food processing, and cosmetics industries [30]. These dyes were ultimately found their way into water bodies, thereby affecting human health, and causing the death of water ecosystems.…”

The novel copper nanoparticles (CuNPs) were synthesized using aqueous leaf extract of Ageratum houstonianum Mill. (AHLE). The green synthesized AH-CuNPs have a useful dye degradation property in the existence of daylight. The photocatalytic activity of AH-CuNPs was evaluated against an azo dye congo red (CR), whereas, same NPs displayed no effect on other dyes. The CR was completely degraded within 2 h, and the reaction rate was followed by pseudo-first-order kinetics, and the rate constant was recorded 3.1× 10 −4 s −1 , (R2=0.9359). Antibacterial activity of green synthesized AH-CuNPs was studied against gram-negative bacterium Escherichia coli (MTCC no. 40), and a significant growth inhibition was recorded with 12.43±0.233 mm zone of inhibition. The AH-CuNPs were characterized through UV-visible spectroscopy, XRD, SEM, FT-IR, TEM, and zeta particle size analyzer. Ageratum houstonianum mediated green synthesized copper nanoparticles (AH-CuNPs) were cubic, hexagonal, and rectangular in shape, with average size of ∼80 nm. The optical band gap was 4.5 eV, which was investigated using UV-visible spectroscopy, and the band gap value revealed that AH-CuNPs were semiconductor materials.

Introduction In recent years, metallic nanoparticles (NPs) have drawn the attention of researchers due to their significant applications in the field of material science, life science, agriculture, and pharmaceutics [1-3]. The amalgamation of biological technique with metal NPs has generated a new area of nanomedicine [4]. The unique characters of NPs like, high yield strength, high surface-to-volume ratio, rigidity, flexibility, specific magnetization, and quantum size are remarkable and contrary to bulk materials with the same chemical composition [5]. Among the metal NPs, copper nanoparticles (CuNPs) have maintained to attain public interest due to its high electrical conductivity, low electrochemical migration, magnificent solderability, high melting point [6], optical, and catalytic properties [7], being used in sensors [8], solar cells [9], information storage [10], heat transfer systems [11], textiles [12], water treatment [13], and antimicrobial coating material in surgical tools [14]. In addition, the synthesis of CuNPs is cheaper when compared to other noble metal NPs of platinum (Pt), silver (Ag), and gold (Au). Various physicochemical methods are used for the synthesis of NPs, which include thermal decomposition [15], electrochemical reduction [16], vapor deposition [17], microwave irradiation [18], so...

“…A few studies have previously reported various crystalline sizes according to XRD analysis for Cu NPs biosynthesized using plants extracts. Instead of, 16.78 nm for Abutilon indicum extract, 22.5 nm for Coccinia grandis fruit extract, 20 nm for Solanum lycopersicum leaf extract, 8–15 nm for fruit extracts of Ziziphus spina‐christ , 40 nm for aqueous extract of oak fruit hull, and 12 nm have been reported for Syzygium aromaticum bud extract …”

“…In our review of the literature, we found different sizes reported for biosynthesized Cu NPs using plant extracts, for example 20-50 nm for synthetic Cu NPs using Olea europaea leaf extract, [23] 15-20 nm for extract of Punica granatum, [24] 10-100 nm for Punica granatum peel extract, [25] 20-60 nm for coffee powder extract, [26] 20-40 nm for Solanum lycopersicum leaf extract, [27] 5-20 nm for Z. spina-christi extract [28] 21.50-34.23 nm for aqueous extract of oak fruit hull, [29] and 20 nm for Syzygium aromaticum. [30] In FT-IR spectra, the peaks in the region between 500 and 700 cm −1 are attributed to metal-oxygen vibration. In this study, copper oxide nanoparticle formation is confirmed by the presence of peaks at 569 cm −1 for the bending vibration of Cu(II)-O [31,32] and at 621 cm − 1 for the bending vibration of Cu(I)-O.…”

The development of nanotechnology has generated different nanoscale‐sized materials, with metal‐based nanomaterials being some of the most interesting and promising. Thousands of articles in various specialized journals all over the world are dedicated to different metallic nanomaterials. Metallic nanomaterials are being widely researched, with gold‐, silver‐, iron‐, and copper‐based materials showing potential in medicine. Studies have demonstrated the effect of copper nanoparticles in medicinal herbs on the prevention, control, and treatment of microbial diseases. Experiments have examined the chemical characterization and assessment of the antioxidant, cytotoxicity, antibacterial, and antifungal activities of copper nanoparticles (Cu NPs) using the aqueous extract of Stachys lavandulifolia Vahl flower. These nanoparticles were characterized by UV–visible spectroscopy, field emission scanning electron microscopy (FE‐SEM), energy dispersive X‐ray spectroscopy, transmission electron microscopy (TEM), Fourier‐transform infrared spectroscopy (FT‐IR), and X‐ray diffraction analysis. TEM and FE‐SEM images exhibited a uniform spherical morphology and diameters of 10–25 nm for the biosynthesized nanoparticles. FT‐IR results suggested polysaccharides and protein in S. lavandulifolia acted as reducing agents, reducing copper ions to Cu NPs. In vitro biological experiments indicated that Cu NPs have excellent antioxidant potential against 2,2‐diphenyl‐1‐picrylhydrazyl, antifungal effects against Candida krusei, Candida parapsilosis, Candida guilliermondii, Candida glabrata, and Candida albicans, and antibacterial activities against Staphylococcus aureus, Enterococcus faecalis, Staphylococcus saprophyticus, Bacillus subtilis, Streptococcus pneumonia, Escherichia coli O157:H7, Salmonella typhimurium, Listeria monocytogenes, Proteus mirabilis, and Pseudomonas aeruginosa. These nanoparticles did not have cytotoxicity properties against human umbilical vein endothelial cells. These results indicate that the inclusion of S. lavandulifolia extract ameliorates the solubility of Cu NPs, which leads to a remarkable enhancement in fungicidal and bactericidal effects under in vitro conditions.

Green synthesis of metal oxide nanoparticles has been emerging highlight of the research owing to its unique properties that make them applicable in various fields of science and technology. The method of synthesis is simple, cost effective and environmental friendly. After review, we reported the phyto-synthesis of metal oxide nanoparticles using plant extract with an emphasis on recent developments. Biomolecules such as alkaloids, flavonoids, polyphenols etc. present in the plant extract can be used for the reduction of metal ions to nanoparticles in a single step process. These extract also act as a stabilizing agent. Although, a good number of work has been reported for the synthesis of gold and silver nanoparticles. However, limited no of work has been reported for the synthesis of copper, zinc and iron oxide nanoparticles. We have discussed the green synthesis of copper, zinc and iron oxide nanoparticles and potential of their antibacterial efficacy
