“…After use, man-made nanoparticles will end up in the environment and may cause specific adverse effects (list in Table 5). Moreover, nanoparticles exploited for environmental engineering applications (e.g., bioremediation [270], fertilizers [271], plant growth enhancers [272], seed quality improvement [273]), may also display toxicity towards the environment and the organisms present in the ecosystem [274]. In few cases, nanoparticles toxicity can be directly visualized at the environmental site.…”

Nanomaterials are becoming important materials in several fields and industries thanks to their very reduced size and shape-related features. Scientists think that nanoparticles and nanostructured materials originated during the Big Bang process from meteorites leading to the formation of the universe and Earth. Since 1990, the term nanotechnology became very popular due to advances in imaging technologies that paved the way to specific industrial applications. Currently, nanoparticles and nanostructured materials are synthesized on a large scale and are indispensable for many industries. This fact fosters and supports research in biochemistry, biophysics, and biochemical engineering applications. Recently, nanotechnology has been combined with other sciences to fabricate new forms of nanomaterials that could be used, for instance, for diagnostic tools, drug delivery systems, energy generation/storage, environmental remediation as well as agriculture and food processing. In contrast with traditional materials, specific features can be integrated into nanoparticles, nanostructures, and nanosystems by simply modifying their scale, shape, and composition. This article first summarizes the history of nanomaterials and nanotechnology. Followed by the progress that led to improved synthesis processes to produce different nanoparticles and nanostructures characterized by specific features. The content finally presents various origins and sources of nanomaterials, synthesis strategies, their toxicity, risks, regulations, and self-aggregation.

“…It can be noted that the majority of AgNPs synthesized via physical and chemical approaches are identified to be toxic or leads to adverse effects on the environment (soil/ water) and affect seed germination and crop yield [82][83][84][85]. The major advantage of utilizing microbial extracts is the toxicity reduction on the prepared nanoparticles and the ability to use less energy when compared to physical and chemical approaches.…”

Graphical abstract Numerous viral infections are common among humans, and some can lead to death. Even though conventional antiviral agents are beneficial in eliminating viral infections, they may lead to side effects or physiological toxicity. Silver nanoparticles and nanocomposites have been demonstrated to possess inhibitory properties against several pathogenic microbes, including archaea, bacteria, fungi, algae, and viruses. Its pronounced antimicrobial activity against various microbe-mediated diseases potentiates its use in combating viral infections. Notably, the appropriated selection of the synthesis method to fabricate silver nanoparticles is a major factor for consideration as it directly impacts antiviral efficacy, level of toxicity, scalability, and environmental sustainability. Thus, this article presents and discusses various synthesis approaches to produce silver nanoparticles and nanocomposites, providing technological insights into selecting approaches to generate antiviral silver-based nanoparticles. The antiviral mechanism of various formulations of silver nanoparticles and the evaluation of its propensity to combat specific viral infections as a potential antiviral agent are also discussed.

“…The intensive literature study revealed that there exists a distinct research gap, that nanoparticles up regulate the plant metabolism [17]. The toxicity of nanoparticles hence becomes different for every crop, the threshold values for different crops are still undiscovered [18]. To address this research gap, this study proposed a novel method that solely works in such a way that it observes the nanoparticle threshold value for different types of biosynthesized nanoparticles.…”

Background A pot experiment was conducted to evaluate the phytotoxic thresholds of zinc oxide (ZnO NPs), iron oxide (FeO NPs), copper (Cu NPs), and silver nanoparticles (Ag NPs) on cotton. All the nanoparticles were biosynthesized from Conocarpus erectus L. leaf extract. They were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and Fourier transmission infrared spectroscopy (FTIR). Five concentrations (0, 25, 50, 75, and 100 ppm) of all the biosynthesized nanoparticles were foliar applied thrice over the duration of cotton growth. Five cotton seeds were sown in 5 kg soil pot and harvested after 6 weeks. SPAD values were evaluated before harvesting while physical growth parameters, physiological parameters biochemical, and oxidative stress parameters were measured after harvesting. Results The value of all parameters, except oxidative stress, increased by 13–47% in response to ZnO NPs application up to 100 ppm. However, phytotoxic threshold of iron oxide nanoparticles (FeO NPs) and copper nanoparticles (Cu NPs) was only 50 ppm as plant growth was increased by 7.9–24.3%. Above 50 ppm plant growth and biomass were decreased by 6.7–16.2%. Silver nanoparticles (Ag NPs) showed maximum growth (3.7 to 9.12% increased) at 25 ppm concentration. At higher concentrations than 25 ppm, the application of Ag NPs decreased the growth due to toxicity. Foliar application of different biosynthesized nanoparticles showed the different range of threshold value for cotton crop. Threshold value of iron oxide and copper nanoparticles for cotton was 50 ppm, whereas, it was 25 ppm for silver nanoparticles. Since the ZnO NPs application continued increasing the growth till its maximum concentration used i.e., 100 ppm, we cannot say that this is its threshold value. Conclusion On the basis of obtained results, it can be concluded that nanoparticles should be used within threshold to avoid adverse effects on crops. Application of nanoparticles within threshold optimum concentration, increased plant biomass and antioxidant system. Graphical Abstract
