“…The sensor's selectivity was evaluated considering as potential interferents the macro constituents of water samples; since the only few changes observed, the selectivity of the nanoparticles toward thiram was proved. A limit of detection of about 0.18 mg/L, lower than the limit value of 7 mg/L proposed by US-EPA, was obtained; so that this method can be promising to detect thiram in natural water and environmental samples [91].…”

Gold and Silver nanoparticles (AuNPs and AgNPs) are perfect platforms for developing sensing colorimetric devices thanks to their high surface to volume ratio and distinctive optical properties, particularly sensitive to changes in the surrounding environment. These characteristics ensure high sensitivity in colorimetric devices. Au and Ag nanoparticles can be capped with suitable molecules that can act as specific analyte receptors, so highly selective sensors can be obtained. This review aims to highlight the principal strategies developed during the last decade concerning the preparation of Au and Ag nanoparticle-based colorimetric sensors, with particular attention to environmental and health monitoring applications.

“…The stem extract of Coscinium fenestratum was used to synthesize AgNPs for treating wastewater; the synthesized AgNPs were used in the detection of fungicide Thiram in wastewater by spectroscopic analysis. These AgNPs also reported an excellent property of degrading methylene blue, methyl orange, and naphthol green B acidic pollutants in wastewater [86]. Extracellular production of AgNPs from a cocktail of fungal extract and characterization was performed.…”

In recent years, nanotechnology has received extraordinary attention as the demands of today’s modern lifestyle are actively changing every day. The need for a sustainable environment and process is the prerequisite today for any advancement. Nanoparticles and its application have extended its wings into various fields. Researchers across the globe are constantly exploring the applications of NPs, especially those of metallic NPs. Among the metallic NPs, silver NPs has received special attention owing to their excellent physical and chemical properties. Nanobiotechnology has opened avenues for such a sustainable and environment-friendly progress. So, in this review, we have summarized the different methods employed in synthesising AgNPs, with special focus on the biological synthesis. This approach is of importance because of its advantages such as use of nontoxic compounds, inexpensive process, and high stability of products obtained in comparison to the other approaches. Several biomolecules of interest such as microbes and plant extracts that are used for synthesis are discussed in detail. The recent advancements in the environmental application of these biologically synthesised NPs include remediation of heavy metals and sensing, as catalysts in toxic dye degradation, remediation of waste water, and also, as a pesticidal agent for crop protection. Although AgNPs have been used in several sectors of research and industries, relevance to the environment is prominent owing to the impact it makes on the humans and all forms of life on earth.

“…Among all the MO NPs, silver (Ag), iron (Fe), zinc (Zn), and cadmium (Cd) NPs have been widely used. Ag are prominent and are widely used in a growing number of applications (Ragam and Mathew 2020;Yu et al, 2013). Many studies have reported negative (Neal 2008;Bradford et al 2009;Coleman et al 2011) or positive (Yin et al 2012;Parveen and Rao 2015) effects of AgNPs on EA.…”

The aim of this work was to study the effect of metal oxide nanoparticles (MO NPs) on enzymatic activities (EAs) of two main plant life forms under drought stress (DS). Foliar spray of silver oxide (AgO), iron oxide (FeO), zinc oxide (ZnO) and cadmium oxide (CdO) at levels of 30, 60, 90 and 120 mg.L-1 were used on aerial parts of forb Sanguisorba officinalis L. and grass Agropyron cristatum (L.) Gaertn. under DS levels of 25-100% field capacity (FC). Glutathione reductase (GR), catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were measured after two weeks of the experiment. The results indicate that the EAs changes varied depending on the plant life form, levels of DS, type and levels of NPs. Overall, application of 30- 60 mg.L-1 MO NPs under 25-50%FC significantly reduced EAs, especially in forb (P<0.001). Higher concentration of MO NPs significantly increase EAs. A decrease in CAT (20.90%, 18.80%), POD (21.30%, 17.67%) and SOD (23.14%, 16.88%) was observed under levels of 60 mg.l-1 of ZnO NPs under 25-50%FC in forb and grass, respectively. High concentration of CdO NPs (90-120 mg.l-1) caused by increase (max= 24.0%) in EAs in both life forms under 25%FC.
