“…[8] The size and shape of nanomaterials depend on the synthesis conditions. Some of the common nanomaterial shapes are nanosphere, [9] nanorod, [10] nanoflower, [11] nanotube, [12] nanowire [13] and nanosheet. [14] Generally, nanomaterials can be either organic (e. g. cellulose, [15] chitosan [16] ) or inorganic materials (e. g. metallic, [17] silicate, [18] or carbonaceous nanomaterials [19] ).…”

Iron‐based magnetic nanoparticles (MNPs) have been studied extensively for the past few decades. They have been applied in various applications, particularly in the biomedical sector. Due to their excellent physical and chemical properties, they have also been used widely in the agricultural sector. MNPs can be synthesized inexpensively and applied in large scale agricultural activities. This paper highlights the applications of iron‐based MNPs in the agricultural sector mainly as antimicrobial agents, plant growth promoters, site‐targeted delivery agents, nanosensors, detection and remediation for pesticide residue. Furthermore, the toxicity and transport of iron‐based MNPs in the soil‐plant system are also elucidated. These aspects have to be well‐understood before MNPs can be fully implemented effectively this pin the agricultural sector. Lastly, a hybrid nanomaterial, which is consisted of iron and magnesium oxide (MgO) nanoparticles (NPs), is proposed. This hybrid nanomaterial is expected to overcome the shortcomings of iron‐based MNPs.

“…Depending on the Zn precursor, plants used for extracts and reaction conditions (usually time and temperature), one can obtain ZnO nanoparticles of various sizes and morphologies. ZnO nanoparticles with flower-like morphologies were obtained using Kalopanax septemlobus , Astragalus membranaceus , Thlaspi arvense , Ruta chalepensis , sea buckthorn fruit extract as reducing/capping agents and zinc acetate or zinc nitrate as salt precursors, in a one-pot synthesis conducted at temperatures varying from room temperature to 70 °C [ 36 , 37 , 38 ]. Other morphologies were obtained when using different combinations of plant extract and Zn salts, such as nanosheets using green tea leaves extract and Zn acetate [ 39 ], hexagonal nanoparticles using Rhamnus Virgata extract and zinc nitrate.…”

Antibacterial and Photocatalytic Properties of ZnO Nanoparticles Obtained from Chemical versus Saponaria officinalis Extract-Mediated Synthesis

In the present work, the properties of ZnO nanoparticles obtained using an eco-friendly synthesis (biomediated methods in microwave irradiation) were studied. Saponaria officinalis extracts were used as both reducing and capping agents in the green nanochemistry synthesis of ZnO. Inorganic zinc oxide nanopowders were successfully prepared by a modified hydrothermal method and plant extract-mediated method. The influence of microwave irradiation was studied in both cases. The size, composition, crystallinity and morphology of inorganic nanoparticles (NPs) were investigated using dynamic light scattering (DLS), powder X-ray diffraction (XRD), SEM-EDX microscopy. Tunings of the nanochemistry reaction conditions (Zn precursor, structuring agent), ZnO NPs with various shapes were obtained, from quasi-spherical to flower-like. The optical properties and photocatalytic activity (degradation of methylene blue as model compound) were also investigated. ZnO nanopowders’ antibacterial activity was tested against Gram-positive and Gram-negative bacterial strains to evidence the influence of the vegetal extract-mediated synthesis on the biological activity.

In this paper, Jr.NiFe2O4 nanoparticles (NPs) were synthesized first time using the leaves extract of Juglans regia via a straightforward process. The physio and phytochemical analysis of plant confirm the presence of macromolecules which function as bio-reductant and stabilize the nanoparticles. The Jr.NiFe2O4 NPs were characterized by UV–visible, FTIR spectroscopy, PXRD pattern, SEM and TGA/DTA analysis. The nanoparticles proved to be optically active having a value of indirect bandgap of energy in the range of 1.53 eV. The Jr.NiFe2O4 NPs have the ability in scavenging 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) free radicals and showed 58.01% ± 1.2% scavenging activity at 100 µg/mL concentrations. The photocatalytic degradation study of ciprofloxacin (CIP) and Congo red (CR) reveals that the highest degradation rate was acquired for CIP using pH = 3, at 254 nm, while 85% of removal rate was analysed for CR. The kinetic studies in case of CR removal followed pseudo-first-order model with thermodynamic parameters (∆G° = − 5.87 kJ mol−1 K, ΔH° = 1393.50 kJ mol−1 and ΔS° = 22.537 kJ mol−1 K) with error analysis. Overall, these data recommend an innovative inspiring application of a plant-mediated synthesis of Jr.NiFe2O4 NPs.
