“…Since algae can make nanoparticles from living and dead materials, they are commonly called bio-nanomaterials. The most commonly used algae for producing metallic nanoparticles include members of the Chlorophyceae, Phaeophyceae, Cyanophyceae, Rhodophyceae, and several kinds of diatoms [57]. Nanoparticles produced by microorganisms have biological uses in the disciplines of bioremediation, biomineralization, bioleaching, and biocorrosion [42].…”

Nanotechnology has attracted remarkable attention due to its unique features and potential uses in multiple domains. Nanotechnology is a novel strategy to boost production from agriculture along with superior efficiency, ecological security, biological safety, and monetary security. Modern farming processes increasingly rely on environmentally sustainable techniques, providing substitutes for conventional fertilizers and pesticides. The drawbacks inherent in traditional agriculture can be addressed with the implementation of nanotechnology. Nanotechnology can uplift the global economy, so it becomes essential to explore the application of nanoparticles in agriculture. In-depth descriptions of the microbial synthesis of nanoparticles, the site and mode of action of nanoparticles in living cells and plants, the synthesis of nano-fertilizers and their effects on nutrient enhancement, the alleviation of abiotic stresses and plant diseases, and the interplay of nanoparticles with the metabolic processes of both plants and microbes are featured in this review. The antimicrobial activity, ROS-induced toxicity to cells, genetic damage, and growth promotion of plants are among the most often described mechanisms of operation of nanoparticles. The size, shape, and dosage of nanoparticles determine their ability to respond. Nevertheless, the mode of action of nano-enabled agri-chemicals has not been fully elucidated. The information provided in our review paper serves as an essential viewpoint when assessing the constraints and potential applications of employing nanomaterials in place of traditional fertilizers.

The current research aimed to study the green synthesis of silver oxide nanoparticles (AgONPs) using Rhynchosia capitata (RC) aqueous extract as a potent reducing and stabilizing agent. The obtained RC-AgONPs were characterized using UV, FT-IR, XRD, DLS, SEM, and EDX to investigate the morphology, size, and elemental composition. The size of the RC-AgONPs was found to be ~ 21.66 nm and an almost uniform distribution was executed by XRD analysis. In vitro studies were performed to reveal biological potential. The AgONPs exhibited efficient DPPH free radical scavenging potential (71.3%), reducing power (63.8 ± 1.77%), and total antioxidant capacity (88.5 ± 4.8%) to estimate their antioxidative power. Antibacterial and antifungal potentials were evaluated using the disc diffusion method against various bacterial and fungal strains, and the zones of inhibition (ZOI) were determined. A brine shrimp cytotoxicity assay was conducted to measure the cytotoxicity potential (LC50: 2.26 μg/mL). In addition, biocompatibility tests were performed to evaluate the biocompatible nature of RC-AgONPs using red blood cells, HEK, and VERO cell lines (< 200 μg/mL). An alpha-amylase inhibition assay was carried out with 67.6% inhibition. Moreover, In vitro, anticancer activity was performed against Hep-2 liver cancer cell lines, and an LC50 value of 45.94 μg/mL was achieved. Overall, the present study has demonstrated that the utilization of R. capitata extract for the biosynthesis of AgONPs offers a cost-effective, eco-friendly, and forthright alternative to traditional approaches for silver nanoparticle synthesis. The RC-AgONPs obtained exhibited significant bioactive properties, positioning them as promising candidates for diverse applications in the spheres of medicine and beyond.

“…In light of the above-surveyed literature, the majority of the investigated works suffer from complexity due to the multistep procedures and problems associated with nanoparticle synthesis, including high costs, not being environmentally friendly, unsustainability and difficult reproducibility of the scale-up process. − Additionally, nanoparticle-based surface modification techniques are likely to be harmful for human health due to nanoparticle release during MD, which causes secondary pollution. , Hence, developing a nanoparticle-free, efficient, and durable omniphobic surface via a single-step technique can be of profound importance. From another point of view, an omniphobic surface with sufficiently low surface energy can be achieved by controlling both surface chemistry and surface roughness.…”

Membrane distillation (MD) provides a promising solution to the worldwide water scarcity through desalination and purification of wastewaters regardless of concentration. However, long-term performance and, therefore, the acceptability of the MD technique are threatened by membrane wetting. Many efforts have been devoted to adressing this crisis through membrane surface modification. In this regard, the simplicity and durability of the modification technique are of paramount importance. In this study, an omniphobic membrane was developed via a single-step nanoparticle-free technique by electrospinning a fluorinated homopolymer, poly(1H,1H,2H,2H-perfluorooctyl acrylate) (PPFOA), on the surface of a poly(vinylidene fluoride) (PVDF) nanofibrous membrane. Actually, electrospinning a lowsurface-energy polymer such as PPFOA makes it possible to simultaneously benefit from surface roughness and surface chemistry towards decreasing surface energy and hence developing an omniphobic surface. It was found that the best results are achieved once the thicknesses of both PVDF and PPFOA layers are optimized. The developed omniphobic membrane with optimized PVDF and PPFOA thicknesses showed outstanding resistance against wetting as evidenced by high water entry pressure (2.2 bar) and large contact angles of 136.5 and 126.3°measured, respectively, for engine oil and isopropanol, the well-known low surface tension liquids. Additionally, despite the pristine PVDF electrospun membrane, the omniphobic membrane exhibited stable air gap MD (AGMD) performance for at least 900 min in direct contact with 3.5 wt % NaCl aqueous solution containing 0.2 mM sodium dodecyl sulfate (SDS).To further evaluate the long-term performance of the optimized omniphobic membrane, the SDS concentration in the MD feed solution was progressively changed from 0.2 to 1.0 mM, and it was observed that the MD process was continued for 720 min with approximately constant flux and salt rejection. To examine the durability of the modification technique, after a long-term evaluation experiment conducted for 15 h, the contact angles of water, engine oil, and isopropanol on the surface of the omniphobic membrane were measured again, and no remarkable changes were recorded. Considering the simplicity and durability of the introduced modification technique, it can be considered a cost-effective and applicable technique to produce omniphobic membranes with low surface energy on a larger scale.
