“…Additionally, the multiple bands corroborate the presence of biomolecules on the surface of BBS-NiONPs which act as capping agents and the peak at 616.36 cm −1 is linked with Ni-O bond formation. These results show uniformity with previous reports [ 21 , 22 , 23 , 24 ]. The BBS-NiONPs showed agglomerated shape which represented the electrostatic interaction of the synthesised NPs with each other.…”

Green synthesis of nanomaterials is advancing due to its ease of synthesis, inexpensiveness, nontoxicity and renewability. In the present study, an eco-friendly biogenic method was developed for the green synthesis of nickel oxide nanoparticles (NiONPs) using phytochemically rich Berberis balochistanica stem (BBS) extract. The BBS extract was rich in phenolics, flavonoids and berberine. These phytochemicals successfully reduced and stabilised the NiNO3 (green) into NiONPs (greenish-gray). BBS-NiONPs were confirmed by using UV-visible spectroscopy (peak at 305 nm), X-ray diffraction (size of 31.44 nm), Fourier transform infrared spectroscopy (identified -OH group and Ni-O formation), energy dispersive spectroscopy (showed specified elemental nature) and scanning electron microscopy (showed rhombohedral agglomerated shape). BBS-NiONPs were exposed to multiple in vitro bioactivities to ascertain their beneficial biological applications. They exhibited strong antioxidant activities: total antioxidant capacity (64.77%) and 2, 2-diphenyl-1-picrylhydrazyl (71.48%); and cytotoxic potential: Brine shrimp cytotoxicity assay with IC50 (10.40 µg/mL). BBS-NiONPs restricted the bacterial and fungal pathogenic growths at 1000, 500 and 100 µg/mL. Additionally, BBS-NiONPs showed stimulatory efficacy by enhancing seed germination rate and seedling growth at 31.25 and 62.5 µg/mL. In aggregate, BBS extract has a potent antioxidant activity which makes the green biosynthesis of NiONPs easy, economical and safe. The biochemical potential of BBS-NiONPs can be useful in various biomedical and agricultural fields.

Chemically nickel oxide nanoparticles (NiONPs) involve the synthesis of toxic products, which restrict their biological applications. Hence, we developed a simple, eco-friendly, and cost-efficient green chemistry method for the fabrication of NiONPs using fresh leaf broth of Rhamnus triquetra (RT). The RT leaves broth was used as a strong reducing, capping, and stabilizing agent in the formation of RT-NiONPs. The color change in solution from brown to greenish black suggests the fabrication of RT-NiONPs which was further confirmed by absorption band at 333 nm. The synthesis and different physicochemical properties of RT-NiONPs were investigated using different analytical techniques such as UV-Vis (ultraviolet−visible spectroscopy), XRD (X-ray powder diffraction), FT-IR (Fourier-transform infrared spectroscopy), SEM (scanning electron microscopy), TEM (transmission electron microscopy), EDS (energy-dispersive X-ray spectroscopy), DLS (dynamic light scattering) and Raman. Further, RT-NiONPs were subjected to different in vitro biological activities and revealed distinctive biosafe and biocompatibility potentials using erythrocytes and macrophages. RT-NiONPs exhibited potential anticancer activity against liver cancer cell lines HUH7 (IC50: 11.3 µg/mL) and HepG2 (IC50: 20.73 µg/mL). Cytotoxicity potential was confirmed using Leishmanial parasites promastigotes (IC50: 27.32 µg/mL) and amastigotes (IC50: 37.4 µg/mL). RT-NiONPs are capable of rendering significant antimicrobial efficacy using various bacterial and fungal strains. NiONPs determined potent radical scavenging and moderate enzyme inhibition potencies. Overall, this study suggested that RT-NiONPs can be an attractive and eco-friendly candidate. In conclusion, current study showed potential in vitro biological activities and further necessitate different in vivo studies in various animal models to develop leads for new drugs to treat several chronic diseases.

“…Finally, the weak absorption peaks around 709-711 cm -1 are related to the stretching vibration of the Ni-O bond in doped NiO. The band at 419 cm -1 is corresponding to the stretching vibrational mode of Mg-O bond [19][20][21][22]. After decorating F-MWCNT with Mg-NiO, it was observed the appearance and disappearance of some absorption peaks in FTIR spectrum.…”

Here we report a novel nanocomposite composed from Mg-doped NiO and Mg-doped\MWCNT using a facile sol-gel method. The synthesized Mg-doped NiO and Mg-doped\MWCNT nanocomposite was characterization by XRD diffraction (XRD), energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and UV–Vis spectrophotometer. The X-Ray analysis revealed that the formation of nanocomposites, which has a cubic phase and a high crystalline nature. The FE-SEM images confirmed the success of decoration the 6%Mg- doped NiO on the surface of the treated MWCNT through the emergence of spherical shapes over the cylindrical tubes. Conversely, optical measurements reveal that the energy gap value for the Mg-NiO and the Mg/NiO-MWCNT nanocomposite are 3.28 and 2.82 eV, respectively. This indicates decreasing the zone between conduction band and valance band. Moreover, it found that Mg doped NiO\MWCNT nanocomposite showed high removal efficiency towards the lead element compared with the Mg-doped NiO. Also, MTT test was employed to study antitumor activity against MCF-7 and WRL68 cells. Our results showed that the Mg doped NiO-MWCNT had cell viability of 66.7 and 71.9% against MCF-7 and WRL68, respectively. Whereas, Mg-doped NiO sample showed cell viability of 70.2 and 71.9% against MCF-7 and WRL68, respectively.
