Purpose
Recent advances in nanotechnology have given rise to the potential utilization of nanoparticles as food, nano-medicine/biomedicines.
Patient
The study aimed to investigate the effects of nano-zinc oxide (nano-zinc) on the bio-assimilation of mineral (Zn) in mice, aged 3–6 weeks.
Methods
ZnO nanoparticles were added to the basal diet as a supplement at amounts of 0.07, 0.14 and 0.21 mg/kg. The synthesized material was characterized by Fourier transform infrared spectrophotometer, particle size, scanning electron microscope, Thermogravimetric Analysis Thermal, X-ray diffraction spectrophotometer and Zeta potential.
Results
In-vitro bioavailability of synthesized group ZnO (120 nm) was 43%, whereas for standard group ZnO (50 nm) was reported as 55%. In-vivo bioavailability of zinc oxide illustrated the maximum absorption level compared with the control. In-vivo toxicity was characterized as damage done to the liver and spleen tissues with a high dose of 0.21 mg/kg, while smaller doses indicated no toxic effects.
Conclusion
The study provided important insights on the toxicological effects of ZnO nanoparticles, depending on dose rate and bio-assimilation, as well as particles, under various conditions (in-vitro and in-vivo). These findings will motivate further detailed research on nano-based medicine for alleviating malnutrition conditions.

“…The dislocation density () in nanocomposites was determined by using Equation 19 [ 67,69 ] :Dislocation density calculated in Sm 2 O 3 /GO and Sm 2 O 3 /rGO nanocomposites were 0.15 and 0.014 nm −1 , respectively. Dislocation density was increased with increasing strain value while decreasing crystallite size (Table 2).…”
This study mainly focuses on the synthesis of two allotropes of graphene, graphene oxide (GO) and reduced graphene oxide (rGO), by the modified Hummers' method and chemical reduction method, respectively. Sm 2 O 3 /GO and Sm 2 O 3 /rGO nanocomposites were further synthesized in the presence of the cationic surfactant CTAB via the sol-gel method followed by the reflux method. Synthesized nanocomposites were subjected to characterization by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and UV-Visible spectroscopy to explore structural, thermal, optical, and photocatalytic properties. Characteristic FTIR peaks were observed in nanocomposites, and the bond length of the Sm-O bond was calculated. The Coats-Redfern method was employed to calculate the kinetics and thermodynamic parameters. Hexagonal crystallite shapes of Sm 2 O 3 /GO and Sm 2 O 3 /rGO nanocomposites with 11.8 and 13.13 nm crystallite sizes and 3.9 and 2.5 eV optical band gaps were observed. The photocatalytic efficiency of Sm 2 O 3 /GO and Sm 2 O 3 /rGO nanocomposites was assessed against the degradation of methylene blue in the presence of sunlight, and its degradation was confirmed through FTIR. The antimicrobial activities were also performed against the bacterial strains Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus.
“…A variety of metal, metal oxides such as ZnO (Goh et al, 2011), Ag (Iqtedar et al, 2019), Fe (Mubeen & Farrukh, 2023), TiO 2 (Adnan et al, 2010) have been used in the past to modify the surface of GO. CuO is a p‐type metal oxide which is ecofriendly, economical and involves easy preparation but due to fast electron hole pair recombination its catalytic applications are reduced (Lucchesi Schio et al, 2021; Younas et al, 2017). Table 1 shows the synthesis of different nanomaterials by using plants extract.…”
The present exploration demonstrates the efficient, sustainable, cost‐effective, and environment‐friendly green approach for the synthesis of silver (Ag)‐doped copper oxide (CuO) embedded with reduced graphene oxide (rGO) nanocomposite using the green one‐pot method and the green deposition method. Leaf extracts of Ficus carica and Azadirachta indica were used for both methods as reducing and capping agents. The effect of methodology and plant extract was analyzed through different characterization techniques such as UV‐visible spectroscopy, Fourier transform infrared (FT‐IR) spectroscopy, thermogravimetric analysis (TGA), x‐ray diffraction (XRD) analysis, scanning electron microscopy (SEM), high‐resolution transmission electron microscopy (HRTEM). The lowest band gap of 3.0 eV was observed for the Ag/CuO/rGO prepared by the green one‐pot method using F. carica. The reduction of graphene oxide (GO) and the formation of metal oxide was confirmed through functional group detection using FT‐IR. Calculation of thermodynamic parameters showed that all reactions involved were nonspontaneous and endothermic which shows the stability of nanocomposites. XRD studies revealed the crystallinity, phase purity and small average crystallite size of 32.67 nm. SEM images disclosed that the morphology of the nanocomposites was spherical with agglomeration and rough texture. The particle size of the nanocomposites calculated through HRTEM was found in agreement with the XRD results. The numerous properties of the synthesized nanocomposites enhanced their potential against the degradation of methylene blue, rhodamine B, and ciprofloxacin. The highest percentage degradation of Ag/CuO/rGO was found to be 97%, synthesized using the green one‐pot method with F. carica against ciprofloxacin, which might be due to the lowest band gap, delayed electron–hole pair recombination, and large surface area available. The nanocomposites were also tested against the Gram‐positive and Gram‐negative bacteria.Research Highlights
