“…Some other examples of vegetable extracts used in NPs production are Malus domestica , Vitis vinifera and Solanium nigrum , whose extracts have been used to synthesize successfully iron NPs [ 132 ]. Recently, an ecological and interesting biosynthesis of stable FeNPs, ranging between 2–30 nm, derived from Phoenix dactylifera L. extract has been published by Prof. Guerrero’s Laboratory, acting as important reducing and capping agents bearing significant antioxidant activity [ 141 ].…”

The unique properties that nanoparticles exhibit, due to their small size, are the principal reason for their numerous applications, but at the same time, this might be a massive menace to the environment. The number of studies that assess the possible ecotoxicity of nanomaterials has been increasing over the last decade to determine if, despite the positive aspects, they should be considered a potential health risk. To evaluate their potential toxicity, models are used in all types of organisms, from unicellular bacteria to complex animal species. In order to better understand the environmental consequences of nanotechnology, this literature review aims to describe and classify nanoparticles, evaluating their life cycle, their environmental releasing capacity and the type of impact, particularly on living beings, highlighting the need to develop more severe and detailed legislation. Due to their diversity, nanoparticles will be discussed in generic terms focusing on the impact of a great variety of them, highlighting the most interesting ones for the industry.

In this study, green synthesis of silver /silver oxide nanoparticles was successfully prepared from Phoenix Dactylifera L aqueous leaves extract. The effect of different volume ratio (% v/v) (Plant extract / Precursor) on the nanoparticles silver /silver oxide nanoparticles formation, optical properties, and catalytic activity for dye degradation was studied. The obtained Ag/Ag2O nanoparticles were characterized using various techniques, such as UV-Visible, FT-IR, XRD, SEM for this purpose. The UV-Vis spectrum shows the absorption at 430 nm associated with Ag/Ag2O NPs. The optical bandgap values were found to be in the range of 3.22 to 4.47 eV for the direct bandgap and 3.73 to 5.23 eV for the indirect bandgap. The functional groups present in plant extracts were studied by FTIR. XRD confirmed the crystalline nature of Ag / Ag2O NP, and its average particle size was between 28.66-39.40 nm. SEM showed that the green synthesized silver/silver oxide nanoparticles have a spherical shape. The purpose of this study, it highlights the high catalytic activity for dye degradation of Ag/Ag2O NPs green synthesized. As a result, the use of Phoenix Dactylifera L aqueous leaves extract offers a cost-effective and eco-friendly method.

“…Recent studies clarifies that plant extracts of Solanum trilobatum, Ziziphora tenuior, Persia Americana, Abutilon indicum, Azadirachta indica, Camellia sinensis and green tea leaves were utilized for the synthesis of IONPs of different size range (Khalil et al, 2017;Arularasu et al, 2018). Current reports also speculate that nanoparticles which are synthesized by using plant extracts are much more stabilized than the conventionally synthesized nanoparticles (Bibi et al, 2019) and are usually of distinct shapes like spherical, cubical, cylindrical, needles, stems, prisms and dendrites (Abdullah et al, 2020). The features of synthesized nanoparticles mainly depends on the discrete criterions like type of the plant extract, volume ratio of the extract and metallic salt solutions and reaction conditions (pH, temperature and incubation time) (Abdullah et al, 2020;Singh et al, 2018).…”

Green approach has received major attention for the synthesis of metal oxide nanoparticles. One such metal oxide nanoparticles are iron oxide nanoparticles (IONPs). IONPs have fetched a great deal of interest in recent era because of their magnetic nature, as they can be easily recovered from the reaction mixture by applying an external magnetic field. Although, a variety of chemical and physical methods of synthesis are known, green synthesis is safer, sustainable and biologically acceptable. Plants and microbes are the main biological materials used for the green synthesis. In present review, the synthesis of IONPs by using plants, bacteria, fungi and algae have been highlighted. IONPs produced by plants, fungi, bacteria and algae usually falls in 1–100 nm range and are of distinct shapes like cubic, tetragonal crystalline, spherical, cylindrical, elliptical, octahedral, orthorhombic, hexagonal rods, nanosphere and quasi spherical. Furthermore, these biomaterials play role of reducing, capping, stabilizing and fabricating agents in green synthesis of nanoparticles. The review put forward a comprehensive report of various routes used for synthesizing IONP, biologically. Intuition into the procedures for synthesis of nanoparticles will help to nourish our learning in the area of nanotechnology.
