“…The presence of organic matter, including proteins in the biogenic TeNPs, was evidenced by FTIR analysis. Bands at 1656 cm −1 and 1539 cm −1 are mainly associated with a C-O stretching peptide bonds from amide I and N-H bending and C-N stretching vibration from amide II, respectively [ 69 , 70 , 71 ]. The band at 2933 cm −1 donates the C-H asymmetric stretching of alkanes [ 72 ].…”

The biosynthesis of nanoparticles using green technology is emerging as a cost-efficient, eco-friendly and risk-free strategy in nanotechnology. Recently, tellurium nanoparticles (TeNPs) have attracted growing attention due to their unique properties in biomedicine, electronics, and other industrial applications. The current investigation addresses the green synthesis of TeNPs using a newly isolated mangrove-associated bacterium, Gayadomonas sp. TNPM15, and their impact on the phytopathogenic fungi Fusarium oxysporum and Alternaria alternata. The biogenic TeNPs were characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Raman spectroscopy and Fourier transform infrared (FTIR). The results of TEM revealed the intracellular biosynthesis of rod-shaped nanostructures with a diameter range from 15 to 23 nm and different lengths reaching up to 243 nm. Furthermore, the successful formation of tellurium nanorods was verified by SEM-EDX, and the XRD pattern revealed their crystallinity. In addition, the FTIR spectrum provided evidence for the presence of proteinaceous capping agents. The bioinspired TeNPs exhibited obvious inhibitory effect on the spores of both investigated phytopathogens accomplished with prominent ultrastructure alternations, as evidenced by TEM observations. The biogenic TeNPs impeded spore germination of F. oxysporum and A. alternata completely at 48.1 and 27.6 µg/mL, respectively. Furthermore, an increase in DNA and protein leakage was observed upon exposure of fungal spores to the biogenic TeNPs, indicating the disruption of membrane permeability and integrity. Besides their potent influence on fungal spores, the biogenic TeNPs demonstrated remarkable inhibitory effects on the production of various plant cell wall-degrading enzymes. Moreover, the cytotoxicity investigations revealed the biocompatibility of the as-prepared biogenic TeNPs and their low toxicity against the human skin fibroblast (HSF) cell line. The biogenic TeNPs showed no significant cytotoxic effect towards HSF cells at concentrations up to 80 μg/mL, with a half-maximal inhibitory concentration (IC50) value of 125 μg/mL. The present work spotlights the antifungal potential of the biogenic TeNPs produced by marine bacterium against phytopathogenic fungi as a promising candidate to combat fungal infections.

“…Similarly, there are few reports about the biological synthesis of CuO NPs using different fungal extracts such as Trichoderma asperellum , Aspergillus terreus , Trichoderma harzianum , and Stereum hirsutum (Consolo et al 2020 ; Cuevas et al 2015 ; Mani et al 2021 ; Saravanakumar et al 2019 ). Additionally, Bhattacharya et al ( 2019 ), Araya-Castro et al ( 2021 ), and Taherzadeh Soureshjani et al ( 2021 ) documented algae-mediated synthesis of CuO NPs using different algal species including Anabaena cylindrica , Macrocystis pyrifera , Cystoseira myrica , Sargassum latifolium , and Padina australis.…”

Versatile nature of copper oxide nanoparticles (CuO NPs) has made them an imperative nanomaterial being employed in nanomedicine. Various physical, chemical, and biological methodologies are in use for the preparation of CuO NPs. The physicochemical and biological properties of CuO NPs are primarily affected by their method of fabrication; therefore, selectivity of a synthetic technique is immensely important that makes these NPs appropriate for a specific biomedical application. The deliberate use of CuO NPs in biomedicine questions their biocompatible nature. For this reason, the present review has been designed to focus on the approaches employed for the synthesis of CuO NPs; their biomedical applications highlighting antimicrobial, anticancer, and antioxidant studies; and most importantly, the in vitro and in vivo toxicity associated with these NPs. This comprehensive overview of CuO NPs is unique and novel as it emphasizes on biomedical applications of CuO NPs along with its toxicological assessments which would be useful in providing core knowledge to researchers working in these domains for planning and conducting futuristic studies. Key Points • The recent methods for fabrication of CuO nanoparticles have been discussed with emphasis on green synthesis methods for different biomedical approaches. • Antibacterial, antioxidant, anticancer, antiparasitic, antidiabetic, and antiviral properties of CuO nanoparticles have been explained. • In vitro and in vivo toxicological studies of CuO nanoparticles exploited along with their respective mechanisms.

“…Green synthesis of nanomaterials has several advantages, i.e., simple process, low cost, less time and energy synthesis consumption, nontoxic, and environmentally benign . Green synthesis is more efficient, compared to chemical synthesis, in terms of the toxicity of chemical species presented in nanomaterial products. − Nanometer-sized iron oxide is one of few inorganic materials that can easily be synthesized and developed using green synthesis through biological substances. − Several biological substances such as leaf or plant extract, − bacteria, − fungi, − vitamins, − protein, − etc. were found compatible to act as reducing, capping, stabilizing, and fabricating agents in green synthesis of various materials, including nanometer-sized iron oxides .…”

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.
