Abstract

Insecticides kill mosquitoes but damage other animals including humans. Eco-friendly metal nanoparticles may be a plant-based pesticide for vector control. Here, the copper nanoparticles (Cu NPs) synthesized from Nepeta cataria leaves have been investigated for their antibacterial and larvicidal properties. Fourier transforms infrared spectroscopy demonstrated that biochemicals reduced and stabilized nanoparticles by shifting peaks from 1,049 to 1,492 cm −1 , and ultraviolet–visible spectrometry proved that produced Cu NPs had a peak at 550 nm. Transmission electron microscopic and scanning electron microscope showed that the particles are spherical and 23–29 nm in size. X-ray diffraction analysis shows that Cu NPs are crystalline. At a 100 µg·mL −1 concentration, Cu NPs exhibited a higher percentage of inhibition in the order of Escherichia coli ≫ Enterococcus faecalis ≫ Staphylococcus aureus . The lethal concentration (LC 50 ) of the Cu NPs against the larvae of Aedes aegypti, Anopheles stephensi, and Culex quinquefasciatus was determined to be 60.63, 56.58, and 54.32 µg·mL −1 , respectively. This ground-breaking study describes the biological production of Cu NPs utilizing N. cataria leaf extract for the first time. Based on these findings, the bio-synthesized Cu NPs and the aqueous extract of N. cataria may provide a potential alternative method for managing these vector populations. Graphical abstract

Selenium (Se) is indispensable for animals and humans. One option to address Se deficiency is to biofortify plants with Se. Biofortification of forage with Se nanoparticles (NPs) is gaining more attention as an efficient and safe source of Se for livestock. The purpose of this study was to investigate the effect of different concentrations of NPs-Se (0, 30, 50, 100, 150, and 250 mg·L −1 ) on the growth of alfalfa harvested multiple times, and to provide a basis for the production of Se-enriched forages. Applying 50 mg·L −1 concentration of NPs-Se had the best effect on yield over three harvests. Over three harvests, low-dose NPs-Se (30 and 50 mg·L −1 ) application significantly increased peroxidase and superoxide dismutase activities, chlorophyll content and carotenoid content, and significantly decreased malondialdehyde content. The total Se content and Se accumulation in plants at the same harvest showed an upward trend with increasing Se concentration. At the same concentration, from first harvest to third harvest, Se content and Se accumulation showed an initially increasing and then decreasing trend. The evaluation found that foliar application of NPs-Se at 50 mg·L −1 could have the greatest positive effect on the growth and yield of multiple-harvested alfalfa.

Abstract

Quaternary quantum dots (QDs) have recently gained more attention due to their low toxicity, tunable wavelength, reduced or no blueshift emission upon overcoating, improved photoluminescence (PL) quantum yield, and PL lifetime when compared to their binary (II–VI) and ternary (I–III–VI) counterparts. In this work, the aqueous synthesis of ZnCuInS/ZnS–ZnS multi-shell quaternary QDs as a nanosensor for the selective detection of Cu 2+ ions was reported. The as-synthesized QDs were spherical, with a particle diameter of 3.66 ± 0.81 nm, and emitted in the first near-infrared window (725 nm) with an average decay PL lifetime of 43.69 ns. The X-ray diffraction analysis showed that the QDs were of the wurtzite structure, while the Fourier transform infrared spectroscopy confirmed GSH capping through the sulphur–metal bond. Furthermore, the fluorometric study shows that the developed multi-shell QDs were selective towards Cu 2+ ions compared to other metal ions via fluorescence quenching with a limit of detection of 1.4 µM, which is below the acceptable limit in drinking water.

Abstract

The most fascinating product of honeybee is propolis. It has an immense role in dentistry, dermatology, and otorhinolaryngology. The increased popularity of propolis as an important remedy is due to its constituents, which have anti-inflammatory, immunomodulatory, antihepatotoxic, anti-cancerous, antifungal, antioxidant, antidiabetic, and antiviral activities. The diverse biological and pharmacological activities of propolis have piqued the interest of many scientists. Many techniques like gas chromatography-mass spectrometry, chromatography, and spectroscopy are being used to identify different propolis constituents. Flavonoids, phenolic acids, and their esters are the most pharmacologically active molecules of propolis and are known to disrupt the replication machinery of the virus corroborating the anti-coronavirus activity of propolis. The main aim of this article is to provide an insight of the increasing theragnostic uses of propolis and its nanoparticles, including their chemical analysis, diverse biological activities, and the necessity for chemical standardization. In this review, we have focused at the promising effects of propolis, its optimization, and its liposomal formulation as a therapeutic intervention for COVID-19 and its accompanying comorbidities.

Abstract

Among biogenic methods employed for synthesizing various nanoparticles (NPs), gum tragacanth (TGC)-mediated NP production is important. The gum TGC not only qualifies the principles of green chemistry but also embraces unique qualities. In this perspective, the current review concentrates on the composition, uses, and exploitation of gum towards synthesizing metal NP of silver (Ag), gold (Au), palladium (Pd), platinum (Pt), and their characterization (UV-visible absorption spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy). In addition, applications of synthesized NP as a bactericide, catalyst, antioxidant, and peroxidase mimic are emphasized. Ag NP (13 nm) showed antibacterial action against Gram-negative and Gram-positive bacteria at 2–12 μg‧mL −1 . The exploitation of Ag NP as a bactericide makes it a candidate of choice for medicinal and pharmacological applications. The catalytic activity of Pd NP (14 nm) demonstrated borohydride reduction of methylene blue. The gum reduced/capped metal and metal oxide NP serve as redox and photocatalysts for the remediation of toxic pigments and dyes in industrial effluents. At 15 μg‧mL −1 , Pd NP exhibited 1,1-diphenyl-2-picrylhydrazyle radical scavenging activity (95.8%) and served as an artificial enzyme mimic for colorimetric sensing of hydrogen peroxide. The industrial applications of other TGC-based nanocomposites, such as heavy metal sorption, wound dressing, drug carrier, tissue engineering, etc., are mentioned.

Abstract

Iron–carbon microelectrolysis was employed to remove phosphorus in this study. The efficiency, mechanism, influence factors, and feasibility of actual wastewater were investigated. The results showed that iron–carbon microelectrolysis had an excellent phosphorus removal ability. When the initial concentration of PO 4 3 − {\text{PO}}_{4}^{3-} –P was 19.44 mg·L −1 , after 120 min reaction time, the remaining PO 4 3 − {\text{PO}}_{4}^{3-} –P in wastewater was 4.65 mg·L −1 , and the removal rate was 76.05%. The precipitate formed in the reaction was mainly ferric phosphate (FePO 4 ), which had a high recovery value. There was a linear correlation between initial phosphorus concentrations and phosphorus removal velocity. As to actual wastewater, 88.37 ± 0.44%, 89.78 ± 1.88%, and 94.23 ± 0.16% phosphorus removal rates were achieved in the influent of municipal wastewater treatment plant, effluent of secondary sedimentation tank, and actual high salinity wastewater, respectively, after 120 min reaction time. This study provides a new method for phosphorus removal and recovery from wastewater. Graphical abstract Iron–carbon microelectrolysis has an excellent phosphorus removal ability. The precipitate formed in the reaction was mainly ferric phosphate (FePO 4 ) which had a high recovery value.

This review addresses green algae-based gold (Au), iron (Fe), and silver (Ag) nanoparticles (NPs) as eco-friendly nanomaterials to deal with biological, organic, and inorganic environmental contaminants. Among nanotechnological tools that can fully degrade, adsorb, and/or convert pollutants into less harmful structures, AgNPs, AuNPs, and FeNPs deserve highlight for their efficiency and low cost. However, green protocols are preferable to produce them in an eco-friendly manner. Although phycosynthesis is still in its infancy, algae present various advantages as green raw materials to NPs’ synthesis; fast growth rate, low-energy input requirement, low costs, easy and eco-friendly cultivation, and high tolerance to metals are examples. To allow their large-scale application, however, challenges regarding obtaining sufficient biomaterial with good reproducibility, designing protocols to achieve desirable features on NPs, and recovering the biocompatible nanomaterial after use still need attention. Perspectives for the field involve surpassing these limitations, broadening knowledge on synthesis mechanisms, protocols, and new species useful to offer, in the future, commercial eco-friendly, and low-cost phycosynthesized AuNPs, AgNPs, and FeNPs to nanoremediation. The potential of these NPs to deal with environmental contaminants, their advantageous characteristics and biocompatibility, the main limitations associated with their large-scale application, and future prospects for the field will receive attention.
