“…After synthetic NPs are formed, they tend to evolve toward a more stable thermodynamic state, through interacting with surrounding molecules or undergoing physicochemical transformations such as corrosion, aggregation, and dissolution [ 20 ]. NPs start linking with biomolecules (e.g., proteins, peptides, nucleic acids, lipids, metabolites of cellular activities, and natural organic matter), which allows the adsorbing of NPs on surfaces immediately upon contact with a living system [ 82 ]. Expanding attention in the last decade was given to NP interactions within biological environments, as well as NP interactions with ecological components [ 20 ].…”

Strawberry production presents special challenges due the plants’ shallow roots. The rooting stage of strawberry is a crucial period in the production of this important crop. Several amendments have been applied to support the growth and production of strawberry, particularly fertilizers, to overcome rooting problems. Therefore, the current investigation was carried out to evaluate the application of biological nanofertilizers in promoting strawberry rooting. The treatments included applying two different nanofertilizers produced biologically, nano-selenium (i.e., 25, 50, 75, and 100 mg L−1) and nano-copper (i.e., 50 and 100 mg L−1), plus a control (untreated seedlings). The rooting of strawberry seedlings was investigated by measuring the vegetative growth parameters (root weight, seedling weight, seedling length, and number of leaves), plant enzymatic antioxidants (catalase, peroxidase, and polyphenol oxidase activity), and chlorophyll content and its fluorescence and by evaluating the nutritional status (content of nutrients in the fruit and their uptake). The results showed that the applied nanofertilizers improved the growth, photosynthetic pigments, antioxidant content, and nutritional status of the seedlings compared to the control. A high significant increase in nutrient contents reached to more than 14-fold, 6-fold, 5-folf, and 4-fold for Cu, Mn, N, and Se contents, respectively, due to the applied nanofertilizers compared with the control. The result was related to the biological roles of both Se and CuO in activating the many plant enzymes. Comparing the Se with the CuO nanofertilizer, Cu had the strongest effect, which was shown in the higher values in all studied properties. This study showed that nanofertilizers are useful to stimulate strawberry seedling growth and most likely would also be beneficial for other horticultural crops. In general, the applied 100 ppm of biological nano-Se or nano-CuO might achieve the best growth of strawberry seedlings under growth conditions in greenhouses compared to the control. Along with the economic dimension, the ecological dimension of biological nanofertilizers still needs more investigation.

“…Mishra et al 39 reported opposite effects of ZnO-NPs in that the SVI of finger millet seedlings was improved (9180.08) at a treatment of 500 mg L −1 of ZnO-NPs produced in a green manner using C. roseus plant extract, compared to control. Subbaiah et al 38 reported that the maximum SVI of maize was determined at a concentration of 1500 mg L −1 ZnO-NPs as 1923.2, as like Lv et al 46 The authors stated that treatment of ZnO-NPs significantly increased the SVI value of wheat at a concentration of 10 mg L −1 to 94% depending on the increasing ⊍-amylase activities. 46 Overall, the results showed that green-synthesized ZnO-NPs were more beneficial to early growth stage (germination percentage, root and shoot elongation) of wheat at low concentrations while raw-ZnO-NPs showed more positive effects at high concentrations than MC-ZnO-NPs.…”

BACKGROUNDUtilizing the fruit extract of bitter melon (Momordica charantia), zinc nanoparticles (ZnO‐NPs) were synthesized through a green approach, a novel endeavor in current literature. The primary objective was to evaluate the phytotoxic and growth‐promoting effects of these ZnO‐NPs on wheat, chosen as a test plant. Structural characterization using X‐ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy revealed the hexagonal wurtzite crystal structure of ZnO‐NPs and identified spherical M. charantia‐produced (MC)‐ZnO‐NPs ranging in size from 48 to 150 nm.RESULTSAt a concentration of 2000 mg L−1, both MC‐ and raw‐ZnO‐NPs augmented wheat germination percentages. Furthermore, raw‐ZnO‐NPs at 4000 mg L−1 demonstrated the highest chlorophyll content. Despite the plant's increased accumulation of MC‐ZnO‐NPs, no statistically significant toxic effects were observed. The antibacterial efficacy of ZnO‐NPs was assessed against Gram‐positive and Gram‐negative microorganisms. MC‐ZnO‐NPs exhibited a 67.9% inhibition zone against Escherichia coli at 0.04 mg L−1, while raw‐ZnO‐NPs exhibited 75.6% inhibition at the same concentration.CONCLUSIONThe study suggests that ZnO‐NPs synthesized from M. charantia exhibit both growth‐promoting effects on wheat without significant phytotoxicity and potent antibacterial properties, particularly against Escherichia coli. However, further investigations are warranted to comprehensively understand the interactions between ZnO‐NPs and plants. Future research should focus on M. charantia, exploring its enhanced effects on plant growth, development and antibacterial attributes. These findings hold promise for potential agricultural applications, emphasizing the need for detailed phytotoxicological assessments of ZnO‐NPs. © 2023 The Authors.

“…As claimed by a previous study (McGee et al, 2020), the microbial community in acidic soils was far more susceptible to AgNPs exposure than in neutral soil. Zn/ZnO has similar chemical properties to Ag (Lv et al, 2022) and thus had minor inhibition on SIR in alkaline soils, causing a more significant decrease of DOC in alkaline soils (Figures S8a, S10a). However, Ag, Fe/Fe x O y , and Zn/ZnO dissolve more slowly in neutral and alkaline soils despite sulfidation, and the chemical structure of TiO 2 is stable in the environment (Lv et al, 2022;Zhang et al, 2020), which may enhance their transport in soils and increase contact with microorganisms.…”

Terrestrial ecosystems are increasingly being exposed to metallic nanoparticles (MNPs). However, the global‐scale impact of MNPs on soil carbon dioxide (CO2) emission remains unknown, limiting our understanding of the role of MNPs in global carbon cycle. We compiled a dataset comprising 1764 pairs of experimental observations to investigate the effects of MNPs exposure on soil respiration parameters, including respiration rates, related enzyme activities, and microbial variables. We found that MNPs could stimulate or suppress soil basal respiration rates across global environments, depending largely on the type of MNPs. We further showed that, although the inhibition of MNPs on most enzyme activities peaked in short‐term exposure (≤28 days), prolonged exposure to MNPs still inhibited soil organic carbon degradation. Finally, we determined that environmental conditions (e.g., soil pH and presence/absence of plants) were also important regulators of the influence of MNPs on soil respiration parameters. Our findings underline that the effects of MNPs on soil CO2 emission depended on MNPs type, exposure design, and environmental factors, which is critical for predicting the role of MNPs in influencing the global carbon cycle and climate change.
