“…According to FTIR analysis, the bioreduction of ferric chloride into iron NPs is due to the reduction of the spinach leaf extract by capping material [38,39]. When these findings were compared to previous reports [40][41][42], it was discovered that the hydroxyl, carboxyl, and amide groups in BPE might be involved in the NP synthesis process.…”

Spinacia oleracea (spinach) and Musa acuminata (banana) were chosen for the study, and aqueous extracts of spinach leaf extract (SLE) and banana peel extract (BPE) were prepared for the synthesis of iron nanoparticles (FeNPs), and their antibacterial potential against pathogenic bacteria Bacillus subtilis (MTTC 1133) and Escherichia coli (MTTC 62) was evaluated. In 10 minutes at 60°C, the color of the mixture (FeCl3+SLE) changed from light green to dark blackish-brown, and the color of the mix (FeCl3+BPE) changed from transparent yellow to dark black, confirming the synthesis of FeNPs from SLE and BPE, respectively. The UV-Vis spectra of spinach- and banana-derived FeNPs revealed two peaks ranging from 240 to 430 nm and multiple peaks at 240, 270, and 395 nm, respectively. FTIR spectroscopy was used to show different functional groups on BPE and SLE, and their role in FeNP synthesis was predicted. TEM micrographs showed that the particles were in nanoscale, ranging in size from 20 to 50 nm for BPE-derived FeNPs and 10 to 70 nm for SLE-derived FeNPs. The FeNP (BPE and SLE) XRD analysis revealed amorphism, with a weak iron characteristic peak, indicating noncrystallinity. The antibacterial potential of BPE- and SLE-FeNPs was investigated, and inhibition zones (mm) against B. subtilis ( 22.70 ± 0.4 ) and E. coli ( 20.45 ± 1.66 ) were observed, as well as SLE-FeNPs against B. subtilis ( 23.56 ± 1.00 ) and E. coli ( 20.33 ± 0.58 ). There were no significant differences in antibacterial activities between BPE-FeNPs and SLE-FeNPs. Positive controls were tetracycline and gentamicin, both standard antibiotics, at 5 μg/disk. SLE- and BPE-derived green FeNPs were also analysed in vivo of D. melanogaster life history traits, i.e., fecundity, hatchability, viability, and duration of development for toxicity evaluation. SLE- and BPE-derived green FeNPs at a concentration of 10 mg/L were fed flies compared to normal diet-fed flies (control sample), and no significant differences were observed between them. The findings suggest that FeNPs have a high antibacterial potential and could be used as antibacterial agents against pathogenic bacteria while being nontoxic in nature.

“…The sizes of iron oxide nanoparticles are important, whether they can be called 3D or 0D materials, as we mentioned in the previous section. Therefore, many results of iron oxide in 3D nanoparticles synthesized using the green approach have been reported previously, , as shown in Figure d. This is including iron oxide nanoparticles with different shapes, such as spherical, hexagonal, cubes, core–shell, porous spheres, nanohusk, distorted cubes, and self-oriented flowers .…”

Iron oxides are old but gold. Stacks of review articles have been published with regard to sounding the magnificence of iron oxides for many applications. Nevertheless, no existing review papers discuss more specifics on how to fabricate nanometer-sized iron oxides, which, in fact, we can obtain them directly from natural sources and wastes via green technology. Direct synthesis of nanometer-sized iron oxides from natural sources and wastes could simply make them less expensive, and, of course, significantly decrease the energy requirement in the synthesis process, lower time synthesis consumption, and be environmentally benign. Here, we compile and synthesize all information on nanometer-sized iron oxides, starting from their phase diversity and their low-dimensional forms such as in zero-, one-, two-, and three-dimensional (0D, 1D, 2D, and 3D, respectively) shapes. Furthermore, the synthesis of nanometer-sized iron oxides from natural sources and waste materials via green synthesis is explained comprehensively, followed by the elucidation of the prospect and challenges of each synthesis method. Lastly, the recent applications and potential commercialization of nanometer-sized iron oxides synthesized from natural sources and waste materials from the point of view of green technology are also listed in this review article.

“…Green nanotechnology‐driven therapeutic systems include inorganic metallic NPs, polymeric NPs, mesoporous silica NPs, quantum dots, solid lipid NPs, lipid nanocarriers, and dendrimers. Recently published review articles in this regard have focused either on plants, biomolecule‐based synthesis of specific metallic NMs (Bolade et al, 2020; Carrion et al, 2021; Din et al, 2020; Du et al, 2020; Jadoun et al, 2021; Nande et al, 2021; Schneider et al, 2021; Siddiqi & Husen, 2020), or describing only biomedical applications (Zafar et al, 2020). This review article focuses not only on updated descriptions of plant‐based metallic green NMs incorporating silver, gold, iron, zinc, copper, carbon, platinum, and palladium but also discusses various biomedical applications of green NMs, including their use as antimicrobial and anticancer agents, for diagnostics and drug delivery, and in tissue engineering and regenerative medicine.…”

Nanotechnology has attracted the attention of researchers from different scientific fields because of the escalated properties of nanomaterials (NMs) compared with the properties of macromolecules. NMs can be prepared through different approaches involving physical and chemical methods. The development of NMs through plantbased green chemistry approaches is more advantageous than other methods from the perspectives of environmental safety, animal, and human health. The biomolecules and metabolites of plants act as reducing and capping agents for the synthesis of metallic green NMs. Plant-based synthesis is a preferred approach as it is not only cost-effective, easy, safe, clean, and eco-friendly but also provides pure NMs in high yield. Since NMs have antimicrobial and antioxidant potential, green NMs synthesized from plants can be used for a variety of biomedical and environmental remediation applications. Past studies have focused mainly on the overall biogenic synthesis of individual or combinations of metallic NMs and their oxides from different biological sources, including microorganisms and biomolecules.Moreover, from the viewpoint of biomedical applications, the literature is mainly focusing on synthetic NMs. Herein, we discuss the extraction of green molecules and recent developments in the synthesis of different plant-based metallic NMs, including silver, gold, platinum, palladium, copper, zinc, iron, and carbon. Apart from the biomedical applications of metallic NMs, including antimicrobial, anticancer, diagnostic, drug delivery, tissue engineering, and regenerative medicine applications, their environmental remediation potential is also discussed. Furthermore, safety concerns and safety regulations pertaining to green NMs are also discussed.
