“…Samarium nitrate along with Medicago sativa (alfa-alfa) was subjected for the synthesis of NPs at pH 4, 6, 7 and 8. Unagglomeratized 10 nm size stable samarium NPs were obtained at pH 4; in contrast, at pH 6, 7 and 8, samarium NPs were found to be agglomerated and of irregular sizes [115].…”

Nanoparticles (NPs) are elements derived from a cluster of atoms with one or more dimensions in the nanometer scale in the range of 1–100 nm. The bio nanofabrication of metallic NPs is now an important dynamic area of research, with major significance in applied research. Biogenic synthesis of NPs is more desirable than physical and chemical synthesis due to its eco-friendliness, non-toxicity, lower energy consumption, and multifunctional nature. Plants outperform microorganisms as reducing agents as they contain large secondary biomolecules that accelerate the reduction and stability of the NPs. The produced NPs can then be studied spectroscopically (UV-Visible, XRD, Raman, IR, etc.) and microscopically (SEM, TEM, AFM, etc.). The biological reduction of a metallic ion or its oxide to a nanoparticle is quick, simple, and may be scaled up at room temperature and pressure. The rise in multi-drug resistant (MDR) microbes due to the immoderate use of antibiotics in non-infected patients is a major cause of morbidity and mortality in humans. The contemporary development of a new class of antibiotics with different mechanisms of action to kill microbes is crucial. Metals and their oxides are extremely toxic to microbes at unprecedentedly low concentrations. In addition, prevailing infections in plants and animals are raising significant concerns across the globe. NPs’ wide range of bioactivity makes them ideal antimicrobial agents in agricultural and medical fields. The present review outlines the synthesis of metallic NPs from botanicals, which enables the metals to be in a stabilized form even after ionization. It also presents a valuable database on the biofunctionalization of synthesized NPs for further drug development.

“…The soil available Sm concentration was determined using the DTPA extraction method (Carter and Gregorich 2007;Kim et al 2015) based on preliminary experiments (Hu et al 2020). One g of ground soil sample was added to 10 mL of DTPA reagent consisting of diethylenetriaminepentaacetic acid (DTPA) (0.005M), CaCl 2 (0.01M) and triethanolamine (0.1M).…”

“…REE are applied in agricultural activities as crop fertilizers (i.e. phosphate fertilizers), mainly in China (Hu et al 2006;Hu et al 2020). The total concentration of REEs in agriculture soils was 83 to 9840 µg g − 1 (Adeel et al 2019).…”

The mode of action, bioaccumulation potential and toxicity of Rare Earth Elements (REE), with several applications in the technology, medical and agricultural fields, are still understudied. The nitrates acute effects on single exposures, binary and ternary mixtures of lanthanum (La), neodymium (Nd) and samarium (Sm) on Lactuca sativa lettuce seed germination and wet biomass in an artificial soil (AS) and an Ultisol were assessed. Germination (EC50), wet biomass (IC50) and germination inhibition (% GI) were evaluated. EC50 values La was the most toxic in PVA, Sm in AS, and Nd appears with intermediate values on both substrates. The IC50, both single and mixed, decreased from 3- to 181-fold with increasing test concentrations in relation to the control in AS, while increases in Ultisol were observed, followed by decreases at higher doses which may be associated with the low-dose stimulation effect (hormesis). Our findings may be used to subsidize REE risk assessment studies and reinforce the hormesis effect to prevent the use of high application of REE fertilizers, avoiding the accumulation of REE in agricultural soils.
