“…In another research, Nazari An environmentally safe approach for the facile synthesis of anti-mutagenic fluorescent quantum dots: Property investigation and the development of novel antimicrobial applications et al employed Marinospirillum alkaliphilum to synthesize AgNPs and examined its anticancer properties using the brine shrimp assay. According to their studies, the nanoparticles were highly toxic (LC 50 = 1 lg/ml) (Nazari and Jookar Kashi, 2021). We believe that our results are accurate.…”

“…Where h is the Bragg angle (in degrees), b is the angular line width at half maximum intensity (in radians), and k is the X-ray wavelength (in nm). For maximum intensity at 2 h % 38.11, b = 0.00824 rad, k = 1.54 A, and h % 19.05, Scherrer's equation was used to estimate the average size of the Ag nanoparticles, which is estimated to be around 17.90 nm (Nazari and Jookar Kashi, 2021).…”

“…This could be achieved with the immense potential of nanotechnology in various aspects of agriculture such as the management of pests, pathogens, weeds and diseases, plant protection, maintenance of soil and water health, pollution monitoring, improving quality of crops, and developing nano-sensors [ 3 , 4 ]. Silver nanoparticles (AgNPs) have been reported to exhibit peculiar properties with a wide range of applications in agriculture, water purification, air filtration, pharmaceutics, catalysis, and textile industries [ 5 , 6 ] and thereby provide useful platform to explore various interdisciplinary fields. Further, AgNPs can be used as effective antibacterial, antifungal, insecticidal and nematicidal agents [ 4 , 7 ].…”

Meloidogyne incognita (root-knot nematode) is a devastating soil-borne pathogen which can infect almost all cultivated plants around the globe, expediting huge pecuniary losses. The purpose of current study was to use the aqueous root extract of Glycyrrhiza glabra for synthesizing silver nanoparticles (GRAgNPs) and assess their nematicidal potential against M. incognita by in vitro methods, including hatching inhibition and mortality assays. The active uptake of FITC labeled GRAgNPs by the nematode and their effect on the expression of selected genes involved in oxidative stress and DNA damage repair were also studied. An HRTEM micrograph confirmed their spherical morphology with sizes ranging from 9.61 nm to 34.735 nm. Complete inhibition of egg-hatching was observed after 48 h of treatment with as low as 10.0 ppm of GRAgNPs. In addition, 100% mortality was recorded at the lowest dose of 6.0 ppm, after 12 h of treatment. The LC-50 for GRAgNPs was found to be 0.805 ± 0.177 ppm at p < 0.0001, R2 = 0.9930, and α = 0.05. The expression of targeted genes (skn-1, mev-1, sod-3, dhs-23, cyp-450, xpa, cpr-1, gst-n, and ugt) was significantly enhanced (1.09–2.79 folds), at 1.0 ppm (α = 0.05, 95% CI) GRAgNPs treatment. In conclusion, GRAgNPs performed efficaciously and considerably in contrast to chemical nematicide and commercial silver nanoparticles (CAgNPs) and might be used as a promising alternative as relatively lower concentration and short exposure time were enough to cause higher mortality and nanotoxicity in nematodes.

Materials behave in a different way when they are in their nano sizes. Nanomaterials encompass a high surface-to-volume ratio, a high adsorption capacity, high sensitivity, and reactivity, hence these can be efficiently used for textile wastewater treatment. Numerous studies have shown that nanoparticles can effectively eliminate various pollutants of domestic and industrial effluent. Nanoparticles are conventionally synthesized by physical and chemical methods but these methods use toxic chemicals, complicated procedures, and expensive materials. Presently, enzymatic processes are the most preferred method as they are economically cheap and environmentally sustainable. Microorganisms, break down the metal salts into metal nanoparticles, which can be isolated and used for textile dye degradation. This review epitomizes the various biosynthesized metal and metal oxide nanoparticles by different microorganisms and if they are efficient to degrade diverse textile dyes.
