Abstract Biodegradable nanofilms from polyvinyl pyrrolidone (PVP), carboxymethyl cellulose (CMC), citric acid (CA), glycerol (G), and zinc oxide nanoparticles (ZnO-NPs) were prepared using different ZnO concentrations and different electron beam irradiation doses, enabling crosslinking formation. The prepared films were characterized by X-ray diffractometer, Fourier transform infrared spectroscopy, thermogravimetric analyser, and transmission electron microscopy. The swelling percentage of PVP:CMC films was ordered in the sequence of composition ratio 1:2 > 1:1 > 2:1. Results showed decrease in swelling capacity accompanied by increase in gelation percentage of (PVP:CMC)/CA/G)/ZnO nanofilms as the irradiation dose increased up to 20 kGy. The tensile strength of (PVP:CMC) films increased by the incorporation of ZnO-NPs and increasing the irradiation dose. The thermal stability of the prepared (PVP:CMC)/CA/G/ZnO nanofilms was enhanced as the irradiation dosage increased. The water vapour transmission rate of the irradiated films was decreased. The biodegradability of the prepared nanofilms was monitored during 16 weeks and it exceeded 65% weight loss from the original blank weight. Moreover, the nanofilms exhibit antimicrobial activity against fungi, Gram-negative, and Gram-positive bacteria. The broad antimicrobial activity spectrum of the prepared nanofilms increased as the concentration of ZnO-NPs increased. These results suggested that (PVP:CMC)/CA/G/ZnO nanofilms can serve as biodegradable materials in various applications characterized by antimicrobial activity.

Abstract In this article, silicotungstic acid (STA)-loaded metal–organic framework (MOF)-derived composites (C-STA@ZrO2) were successfully synthesized by simple strategies. X-ray diffraction, Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray, N2 physisorption, UV-vis diffuse reflection spectroscopy, and X-ray photoelectron spectroscopy techniques were used to characterize the as-obtained composites. Intriguingly, C-STA@ZrO2 exhibits excellent photocatalytic performance, and rhodamine B (RhB) (40 mg·L−1) in water can be degraded to 93.9% after 120 min of irradiation. Moreover, various catalysts, catalyst dosage, and dye concentrations on RhB degradation were evaluated. Besides, the reusability of C-STA@ZrO2 was also investigated. This work may provide a new and significant guideline for exploring excellent performance of MOF-derived hybrid material for wastewater purification.

Abstract This study intended to optimize apigenin (APG) nanoparticle formulation prepared by planetary ball milling to enhance its dissolution rate and bioavailability using a design of experiment (DoE). In this study, polyvinyl pyrrolidone (PVP K30) was used as a nanoparticle stabilizer. The independent parameters of milling speed, milling ball size, and drug to solvent ratio were evaluated for their impacts on APG nanoparticles concerning the nanoparticle size (Y1), zeta potential (Y2), and drug dissolution efficiency after 60 min, notated as % DE60 (Y3). The milling ball size showed a significant antagonistic effect (P = 0.0210) on the size of APG nanoparticles, while milling speed had an agonistic effect on the zeta potential values of drug nanoparticles, ranging from low to medium speed levels. In addition, ANOVA analysis indicated that the effect of the drug-to-solvent ratio on the % DE60 of APG from the nanoparticle formulations was antagonistically significant (P = 0.015), and the quadratic effect of milling speed (AA) also had a significant antagonistic effect (P = 0.025) on the % DE60. Risk assessment analytical tools revealed that milling ball size and milling speed significantly affect the nanoparticle size. The drug/solvent ratio exerted a strong impact on % DE60. Furthermore, the maximum plasma concentration (C max) of the optimized APG nanoparticle formula increased by four folds. In addition, AUC0–t (ng·mL−1·h−1) for APG nanoparticle (353.7 ± 185.3 ng·mL−1·h−1) was higher than that noticed in the case of the untreated drug (149 ± 137.5 ng·mL−1·h−1) by more than two folds.

Abstract Bio-fortification is a potential technique to tackle micronutrient deficiencies that remain. Wheat grain bio-fortification has the ability to decrease malnutrition because it represents one of the most essential staple crops. Bio-fortification is cost-effective and evidence-based sustainable technique to address malnutrition in wheat varieties possessing additional micronutrient contents. Nano-biofortification is a novel approach, enriching crops with essential nutrients in order to supplement human diets with balanced diets. The current study was designed to explore the potential role of phytogenic iron nanoparticles (Fe-NPs) to enhance nutritional contents in wheat plants to fulfill the nutrient deficiency important for human and animal health. In the current study, Fe-NPs were fabricated by using the extract of Mentha arvensis L. that were irregular in shape with an approximate size range of 40–100 nm. Further, Fourier transform infrared (FT-IR) analyses were deployed to confirm the presence of t of various functional groups involved in the green and eco-friendly fabrication of Fe-NPs. The effects of phytogenic Fe-NPs were examined on various physiological and biochemical parameters such as total proline, total chlorophyll, carbohydrates, protein, crude fibers, and lipids contents. Moreover, wheat physiological and biochemical profiling was carried out, and it was noticed that Fe-NPs significantly altered the physico-biochemical profiling of wheat plants. Multiple methods of administration of Fe-NPs were used to fortify the wheat crop. However, the Fe-NPs assisted seed priming along with foliar applications at various concentrations (10, 20, and 30 mg·L−1) were found more suitable to enhance the contents of proline, Chlorophyll a, b, total chlorophyll, carbohydrate, proteins, fibers, and lipids (20.22%, 18.23%, 17.25%, 16.32%, 12.34%, 24.31%, 19.52%, and 11.97%, respectively) in wheat plants. Further, wheat flour was exposed to digestive enzymes, with the iron content gradually increased in a dose-dependent manner. The nutritional analysis of wheat zinc (Zn), molybdenum (Mo), magnesium (Mg), iron (Fe), yttrium (Y), and copper (Cu) and the fatty acid profile have demonstrated divergent patterns of behavior. Similarly, iron content was also increased significantly in response to the exposure to Fe-NPs.

Abstract Mosquito vectors in the present universe cause a major problem due to the transmission of pathogens with high morbidity. The present research aimed to explore the larvicidal and adulticidal toxicity of the Cladostepus spongiosus extract and its fabricated AgNPs on key mosquito vectors. The synthesized AgNPs were confirmed by UV-Vis spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectrophotometry, and X-ray diffraction analysis. In the mosquitocidal assay, the C. spongiosus extract has shown good larvicidal mortality against Aedes aegypti (88.9%), Anopheles stephensi (84.1%), and Culex. quinquefasciatus (81.6%). Further, adulticidal mortality percentages were 78.8%, 75.4%, and 67.6% against An. stephensi, Ae. Aegypti, and Cx. quinquefasciatus at 1,000 ppm. AgNPs revealed larvicidal mortality percentages of 94.8% against An. stephensi, 92.8% against Ae. Aegypti, and 90.6% against Cx. quinquefasciatus; the adulticidal potential was also revealed to be higher against An. stephensi (89.4%) followed by Ae. aegypti (86.8%) and Cx. quinquefasciatus (83.2%). Comparing the results achieved from the C. spongiosus extract and its derived AgNPs, promising activity was attained against key mosquito vectors at a minimal dose of 70 ppm of AgNPs. Thus, C. spongiosus-mediated AgNPs can be an alternative tool in controlling key mosquito vectors.

Abstract This study assessed the protective effect of citrus flavanone, naringin (Nar), and its nanoformulation against di(2-ethylhexyl)phthalate (DEHP) toxicity in albino rats. Keeping green nanotechnology as the cornerstone, nanoparticles of Nar were synthesized and characterized using electron microscopy (transmission electron microscopy and scanning electron microscopy), particle size distribution, Fourier transform infrared spectroscopy, and X-ray diffraction. The synthesized nanoparticles were primarily spherical with an average size of 109 nm and a low polydispersity index of 0.175. Mature male albino rats were used for the exposure study. Group I was negative control. Groups II, III, and IV were exposed to (250 mg·kg b·wt−1) DEHP for 3 weeks. Group III was treated with bulk Nar (5 mg·kg b·wt−1), and group IV was treated with non-naringin (NNar) (5 mg·kg b·wt−1). Group V was exposed only to NNar. Exposure to DEHP significantly enhanced serum levels of pro-inflammatory cytokines, interleukin-1β, 6, 8 (IL-1β, IL-6, IL-8), and tumour necrosis factor (TNF-α). In addition, the repression of hepatic mRNA expression of nuclear factor-erythroid 2-related factor 2 was also observed. In addition, marked histopathological alterations were observed in the hepatic and renal tissues. Treatment with both Nar and NNar significantly alleviated the DEHP-induced oxidative stress/inflammatory response along with the associated histological alterations. However, therapeutic utility of NNar was more profound underlining its potential in nutraceutical therapeutics with high green credentials.

Abstract In the search for potent bioactive compounds, a series of tetrahydro-2H-1,3,5-thiadiazine-2-thiones (1–13) were synthesized in good yield and characterized by means of 1H NMR, 13C NMR, and mass spectral data. The anticancer activity of the compounds was evaluated against HeLa cell line and anti-inflammatory potential via nitric oxide (NO) inhibition. Among the screened compounds, 2-(5-(3-methoxypropyl)-6-thioxo-1,3,5-thiadiazinan-3-yl) propionic acid (3), 2-(5-cyclopropyl-6-thioxo-1,3,5-thiadiazinan-3-yl) propionic acid (5), 2-(5-cyclopropyl)-6-thioxo-1,3,5-thiadiazinan-3-yl) acetic acid (6), and 2-(5-butyl-6-thioxo-1,3,5-thiadiazinan-3-yl) acetic acid (9) were the most potent against HeLa cell line with IC50 values <4 µM, whereas the rest of the series exhibited moderate-to-good activities. All the compounds were potent NO inhibitors with IC50 values ranging from <0.4 to 14.9 µM. Docking studies, binding orientations, and interaction plots showed strong interaction of the studied compounds with the inducible NO synthase enzyme via strong hydrogen bonds and hydrophobic interactions, which authenticate the in vitro results. These newly synthesized compounds could lead to the discovery of anticancer drugs.

Abstract In this article, Bi2O3@Zn-MOF hybrid nanomaterials were synthesized by supporting Zn-based metal–organic framework (Zn-MOF) through the hydrothermal method. X-ray diffractometer, Fourier transform infrared, scanning electron microscopy, energy-dispersive X-ray, N2 physisorption, X-ray photoelectron spectroscopy, and UV-Vis were used to characterize the physical and chemical properties of Bi2O3@Zn-MOF nanomaterials. The photocatalytic activity of the as-prepared hybrid has been studied over the degradation of rhodamine B (RhB). A catalytic activity of 97.2% was achieved using Bi2O3@Zn-MOF nanocomposite with the loading of 0.18 g Bi2O3, after 90 min of exposure to visible light irradiation, and the high photocatalytic performance was mainly associated with the nanorod structures, larger pore size, and broaden visible light absorption region due to the synergistic effect of the constituting materials. Furthermore, the Bi2O3@Zn-MOF nanocomposite can be reused three times and the degradation rate of RhB was maintained at 77.9%.

The photocatalytic activity of the as-prepared hybrid has been studied over the degradation of rhodamine B (RhB). A catalytic activity of 97.2% was achieved using Bi2O3@Zn-MOF nanocomposite with the loading of 0.18 g Bi2O3, after 90 min of exposure to visible light irradiation, and the high photocatalytic performance was mainly associated with the nanorod structures, larger pore size, and broaden visible light absorption region due to the synergistic effect of the constituting materials.

Abstract Antibiotic-resistant microorganisms are a rising issue when it comes to human health. Microbial pathogens that cause harmful infections are quickly becoming resistant to the antimicrobial action of traditional antibiotics. Nanotechnology, an innovative sector being an indispensable part of healthcare and research, has in-depth and extensive applications. Nano-compounds have been promising antimicrobial agents, anti-cancerous mediators, vehicles for drug delivery, formulations for functional foods, identification of pathogens, food and drug packaging industry, and many more. However, the chemical synthesis of nanoparticles (NPs) has certain drawbacks such as causing toxicity and other adverse effects. For more than a decade, the use of NPs that are conjugated or green-synthesized has gained popularity due to the two-fold action of metallic NPs mixed with biological sources. In contrast, NPs synthesized using plant or microbial extracts, conjugated with biologically active components, appear to be a safe alternative approach as they are environmentally friendly and cost-effective. Such environmentally safe techniques are referred to as “green nanotechnology” or “clean technology” and are feasible alternatives to chemical methods. Furthermore, NPs conjugated with natural biomolecules have improved bioavailability and have minimal side effects, as they are smaller in size and have higher permeability in addition to being reducing and stabilizing agents possessing excellent antioxidant activity. NPs serve as potential antimicrobial agents due to their affinity towards sulphur-rich amino acids, adhere to microbial cell walls by means of electrostatic attraction, and disrupt the cytoplasmic membrane along with the nucleic acid of microbes. They possess anticancer activity owing to oxidative stress, damage to cellular DNA, and lipid peroxidation. The green-synthesized NPs are thus a promising and safe alternative for healthcare therapeutic applications.

Abstract In this article, ZnO quantum dots (QDs)-g-C3N4 complexes were prepared by a combined sol–gel method and ultrasound-assisted chemical method, and ZnO-g-C3N4 composites with different doping ratios were also prepared for photocatalytic degradation of dye wastewater. The composites were characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffractometry, Fourier transform infrared, X-ray photoelectron spectroscopy, diffuse reflectance spectroscopy, and photoluminescence. The photocatalytic performance of the best ZnO QDs-g-C3N4 complexes with different g-C3N4 doping amounts was investigated, and the kinetics of their photocatalytic reactions were analyzed, and it was found that the best effect of ZnO-g-C3N4 10% could reach 89.08% and ZnO QDs-g-C3N4 could reach 91.53%. It was also demonstrated that ZnO-g-C3N4 10%, ZnO QDs-g-C3N4 cyclic stability is better, and the reaction mechanism of ZnO QDs-g-C3N4 was investigated. It can be used for the degradation of dyes in environmental wastewater and the removal of harmful substances from the natural environment.
