“…During synthesis of iron nanoparticles the reduction of Fe 2+ or Fe 3+ ions to Fe 0 is confirmed by visible color change to brown/black depending of nanoparticles concentration in the reaction mixture. Color change indicated the formation of FeNPs physically (Mohamed et al, 2015;Devatha et al, 2016;Ahmad et al, 2017;Asghar et al, 2018;Fahmy et al, 2018). For the four extracellular filtrates used in this study a brown color was revealed in all samples at the end of the assay, but confirmation of FeNPs was carry out by UV-visible spectrophotometer and analysis TEM.…”

“…The peak obtained for FeNPs could varies in the range of 300-500 nm (Devatha et al, 2016). A strong peak at 272 nm was detected during bio-fabrication of iron nanoparticles by using Azadirachta indica leaf (Ahmad et al, 2017), 325 and 296 nm (Devatha et al, 2018), 285 and 324 nm; 216 and 265 nm (Fahmy et al, 2018), 266 and 274 nm (Asghar et al, 2018) all of them using different plant extracts. Magnetic iron oxide (Fe3O4) nanoparticles was biosynthesized using aqueous extract of food processing waste, peaks at 330 and 365 nm from MH-FeNPs, and 325 and 365 nm from CCP-FeNPs were detected, absorption band at 355 nm indicated the formation of nano-sized Fe3O4 NPs (Patra et al, 2017).…”

“…Enzymes as hydrogenases, nitrate reductases, naphthoquinones, and, anthraquinones, has been reported as electron shuttle in metal reductions and production of nanoparticles (Durán et al, 2005). However, other molecules can also be involved in nanoparticle synthesis for instance, reducing sugars, siderophores, quinone, phenols or molecules with antioxidant activity (Korbekandi et al, 2013;Emam et al, 2015;Fahmy et al, 2018). For the extracellular fungal synthesis of nanoparticles, previously fungal biomass is get in stress by putting it in carbon starvation, in this condition the release of biomolecules its promoted toward the aqueous medium, where nanoparticles biosynthesis is carry out.…”

“…The metal nanoparticles (NP) like silver nanoparticles (AgNPs), gold nanoparticles (AuNPs), cadmium sulfide nanoparticles (CdSNPs), iron nanoparticles (FeNPs), etc., are nanomaterials with size less than 100 nm. They have interesting applications in different areas of environmental, medicine, energy, agriculture, chemistry, information, communication, heavy industry, and consumer goods, because they have exclusive optical, thermal, and electrochemical properties (Fahmy et al, 2018). Biosynthesized NPs can also have enhanced stability and biocompatibility and reduced toxicity, mainly due to coating them with biogenic surfactants or capping agents.…”

“…The organisms reported as FeNPs producers are principally plants like Datura inoxia, Calotropis procera, Euphorbia milii, Tinospora cordifolia, Cymbopogon citratus, and Tridax procumbens; the filamentous fungus Aspergillus oryzae and bacterium Acinetobacter spp. (Fahmy et al, 2018). The production of Fe3O4 has been reported by magnetotactic bacteria as Geobacter sulfurreducens, Thermoanaerobacter sp., Thermoanaerobacter ethanolicus and, Magnetospirillum magnetotacticum, has been used to Cr(VI) and Tc(VII) remediation, to enhanced magnetic properties of biosynthesize composite and, cobalt doping of magnetosomes (Schröfel et al, 2014).…”

The ability of four extracellular filtrates (FE), obtained from A. alternata biomass grown in four different culture media; malt dextrose broth (MDB), potato dextrose broth (PDB), sucrose (S) and Czapek (C), were evaluated to biosynthesize iron nanoparticles (FeNPs), at the end of the assay a brown color was revealed in all the samples. To evidence biosynthesis of nanoparticles, absorption spectra were made from 200 to 600 nm for all the samples and, analyzed by transmission electronic microscopy (TEM). The morphology and size of the synthesized FeNPs were studied using the SPIP 6.2.0 software. From the four extracellular filtrates assays, the nanoparticles biosynthesis was possible only in the EF-PDB and EF-C, showing their presence in the UV-vis spectrum when forming an absorption band at 226 and 225 respectively, and plateau around at 270 nm to EF-PDB, and 290 nm to EF-C. The synthesized nanoparticles presented spherical and polydisperse form, those synthesized with EF-PDB showed a size of 20-40 nm, while those synthesized with EF-C had a size of 10-80 nm. Six months after their production, the FeNPs biosynthesized by EF-C were analyzed by microscopy showing an

For the first time, kinetic thermomagnetic extraction is a novel approach presented in this work. It required the application of four distinct variables: rotation speed (50, 75, and 100 rpm), magnetic field (0.8, 1.2, and 1.6 T), time interval (30, 60, and 90 min), and temperature (45, 55, and 65°C). Numerous phytochemical categories were detected in the 81 crude chloroform extracts of green sweet bell pepper seeds that were collected, according to phytochemical analysis. Nine extracts were discovered to be linked to the coumarin chemical class and to have the same two extraction parameters: a 90‐minute extraction duration and a 55°C extraction temperature. To enable their coumarin contents to be chemically separated and chromatographically purified, two of these extracts containing coumarin were chosen. Four new phytocoumarins have been identified and their molecular structures distinguished using FTIR spectra, 1H‐NMR, 13C‐NMR, and mass analysis. The results demonstrated that the extracted phytocoumarins have exceptional oxidative stress‐mitigating characteristics, ranging from 71.51 to 81.48%, when compared to a positive control. Furthermore, they showed excellent cytotoxicity against the test malignant populations (IC50 values of 46.76–81.45 μg/ml). The isolates need to be taken into account as dual COX‐2/5‐LOX antagonists because they also showed a selective anti‐inflammatory effect

Green nanotechnology, an emerging field, offers economic and social benefits while minimizing environmental impact. Nanoparticles, pivotal in medicine, pharmaceuticals, and agriculture, are now sourced from green plants and microorganisms, overcoming limitations of chemically synthesized ones. In agriculture, these green‐made nanoparticles find use in fertilizers, insecticides, pesticides, and fungicides. Nanofertilizers curtail mineral losses, bolster yields, and foster agricultural progress. Their biological production, preferred for environmental friendliness and high purity, is cost‐effective and efficient. Biosensors aid early disease detection, ensuring food security and sustainable farming by reducing excessive pesticide use. This eco‐friendly approach harnesses natural phytochemicals to boost crop productivity. This review highlights recent strides in green nanotechnology, showcasing how green‐synthesized nanomaterials elevate crop quality, combat plant pathogens, and manage diseases and stress. These advancements pave the way for sustainable crop production systems in the future.
