“…Additionally, CuO-Zs-NPs may activate defense mechanisms in response to pathogen inoculation by developing additional proteins to prevent pathogen entry or subsequent spread due to the importance of Cu as a micro-element for plants. Furthermore, recent studies have also demonstrated the role of Cu Bionanoparticles in increasing H 2 O 2 scavenger activity as an anti-resistance mechanism against stress or toxicity(Velsankar et al, 2021). The application of Cu nanoparticles has been shown to enhance antioxidant enzyme activity and reduce oxidative damage caused by stress or toxicity.…”

Incorporating green chemistry concepts into nanotechnology is an important focus area in nanoscience. The demand for green metal oxide nanoparticle production has grown in recent years. The beneficial effects of using nanoparticles in agriculture have already been established. Here, we highlight some potential antifungal properties of Zizyphus spina leaf extract-derived copper oxide nanoparticles (CuO-Zs-NPs), produced with a spherical shape and defined 13–30 nm particle size. Three different dosages of CuO-Zs-NPs were utilized and showed promising antifungal efficacy in vitro and in vivo against the selected strain of F. solani causes tomato root rot disease and is molecularly identified with accession number (OP824846). In vivo, results indicated that, for all CuO-Zs-NPs concentrations, a significant reduction in Fusarium root rot disease occurred between 72.0 to 88.6% compared to 80.5% disease severity in infected control. Although treatments with either the chemical fungicide (Kocide 2000) showed a better disease reduction and incidence with (18.33% and 6.67%) values, respectively, than CuO-Zs-NPs at conc. 50 mg/l, however CuO-Zs- NP at 250 mg/l conc. showed the highest disease reduction (9.17 ± 2.89%) and lowest disease incidence (4.17 ± 3.80%). On the other hand, CuO-Zs-NPs at varied values elevated the beneficial effects of tomato seedlings' vigor at the initial stages and plant growth development compared to either treatment with the commercial fungicide or Trichoderma Biocide. Additionally, CuO-Zs-NPs treatments introduced beneficial results for tomato seedlings' development, with a significant increase in chlorophyll pigments and enzymatic activity for CuO-Zs-NPs treatments. Also, it was indicated that treatment with CuO-Zs-NPs led to a rise in the number of mature pollen grains compared to the immature ones. Even though the data showed that CuO-Zs-NPs have a unique anti-fungal mechanism against F. solani, they nevertheless imply that CuO-Zs-NPs might be a useful environmentally friendly controlling agent for the Fusarium root rot disease that affects tomato plants.

“…CuO NPs interacted with the bacterial membrane due to their nanosize and high surface-to-volume ratio. In this study, the inhibition effect of CuO NPs on gram negative bacteria was found to be greater than that on gram positive bacteria, which could be attributed to differences in bacterial membrane structures [26][27][28][29]. As a result, CuO NPs synthesised from uluva algae extract have been found to be an effective antibacterial agent against gram negative (E. coli) bacteria.…”

“…Fig 1(a-c) shows the XRD pattern of CuO NPs prepared by using Ulva fasciata algae extract at different solvent ratios ( 20 ml, 30 ml and 40 ml). From the fig, eleven diffraction planes were observed at (32˚, 35˚, 38˚, 48˚, 53˚, 58˚, 61˚, 66˚, 68˚, 72˚ and 75˚) and the corresponding hkl planes are (110), (-111), ( 111), (-202), ( 020), ( 202), (-113), (-311), ( 220), ( 311) and ( 004) respectively [16][17][18][19].

An eco-friendly, biogenic synthesis of copper oxide nanoparticles (CuO NPs) using ulva fasciata extract was reported. XRD, FTIR, UV-Vis spectroscopy, SEM, TEM, EDX, antibacterial activity and electrochemical analysis were used to characterize the biosynthesized CuO NPs. XRD spectrum reveals the monoclinic structure. The FTIR spectrum confirms the functional group of CuO NPs. The optical study gives the band gap values of CuO at different concentrations of ulva fasciata algae extract. The antibacterial activities were tested against one gram-positive bacteria S. aureus and one gram-negative bacteria E. coli. The CV curve exhibits a high specific capacitance of 132 F/g, at the scan rate of 10 mV/S.

In this report, ZnO nanoparticles were biosynthesized using Paspalum scrobiculatum grains extract for the first time. GC–MS analysis explicated that diethyl phthalate was the major phytocompound with 94.09% in aqueous extract. ZnO nanoparticles formation was confirmed by various physicochemical analyses. HR‐TEM images showed the hexagonal, rectangular shaped nanoparticles in 15–30 nm size. The antioxidant, anti‐inflammatory, and anti‐diabetic analyses showed the effective bioactivity of ZnO nanoparticles in 80 μg/ml concentration with 95.36%, 94.08%, and 91.96%, respectively. The morphological and tissue changes witnessed in larvicidal and insecticidal activities against Culex tritaeniorhynchus and Tribolium castaneum revealed the efficient nature of ZnO nanoparticles in 100 ppm at 48 h and 100 μg/kg at 72 h, respectively. The morphological changes in antibacterial activity demonstrated the bactericidal nature of ZnO nanoparticles against Salmonella typhi and Staphylococcus aureus in 150 μg/ml concentration. The morphological observations in anticancer activity against HepG2 liver cancer cells showed the potent drug features of ZnO nanoparticles in 100 μg/ml concentration with 97.18% of cytotoxicity. The ZnO nanoparticles showed no toxicity against HDF normal cells in lower concentrations and it explicated the biocompatible features of nanoparticles. The Vigna radiata plant growth was efficiently promoted by low (60 ppm) concentration of nanoparticles. The ZnO nanoparticles divulged effective degradation of IPA, EDTA, BQ, and DPBF in 75%, 45%, 55%, and 80% through ROS formation, respectively. Thus, the synthesized ZnO nanoparticles are biocompatible and inexpensive material compared to the traditional one and can be utilized as an efficient material in biological fields. Research Highlights Efficient larvicidal and insecticidal activities were evinced at low IC50 value. The ZnO nanoparticles were non‐toxic to HDP (fibroblast) normal cells. Efficient plant growth was attained at 60 ppm concentration.
