Nano-selenium was synthesized using lemon juice as a reducing agent. The experiments showed that pH value affected greatly the shape and the size of the prepared nano-selenium. At pH 9, lemon juice could reduce 50 mmol/L of selenite ions to nano-selenium with particle size between 50 and 90 nm, which was spherical and well dispersed. Lemon juice acted as both a reducing agent and a stabilizer in the synthesis of nano-selenium, in which the chemical interaction between biomolecules and the nano-selenium surface was the basis for the stable existence of nano-selenium. The selenite concentration influenced the formation of nano-selenium, and a low selenite concentration was beneficial to obtain small particles. The achieved nano-selenium exhibited a strong antioxidant activity positively related to concentration. The comparative study showed that the antioxidation of nano-selenium is weaker than that of vitamin C but higher than that of lemon juice.

The synthesis of metal nanoparticles by using plant extracts is previously explored in phytomedicines. Nanobiotechnology has many applications, including cosmetic, packing, coating, biomedicine, and enhanced biological activity. Keeping in view the importance of Pistacia chinensis, its gold nanoparticles (AuNPs) have been synthesized by the eco-friendless and cost-effective method. In this study, the synthesized nanoparticles were characterized by advanced techniques such as UV-visible spectroscopy, Fourier transform infrared (FT-IR), and atomic force microscope (AFM) analysis. The biological activities of these synthesized nanoparticles were examined in vitro by measuring the enzymatic inhibition potential on urease and carbonic anhydrase and in vivo by determining the analgesic and sedative activities. The UV spectrum indicated various peaks at the range of 530-550 nm, showing nanoparticles formation. The FT-IR spectroscopy of the extracts and AuNPs indicated the presence of NH, C═N, and N═O in the extract involved in the nanoparticles synthesis. The size of nanoparticles was determined by AFM analysis. The AFM showed that the nanoparticles range from 10 to 100 nm and are almost spherical in shape. The synthesized AuNPs exhibited significant urease inhibition potential with an IC50 value of 44.98. Similarly, the nanoparticles exhibited good carbonic anhydrase inhibition with an IC50 value of 53.54 against acetazolamide having IC50 0.13. Pistacia chinensis extract and its AuNPs exhibited excellent attenuation p < 0.01 in acetic acid-induced writhing model at a dose of 15 mg/kg. The synthesized nanoparticles showed a significant sedative effect p < 0.001 compared to the standard drug. This research work has developed a green method to synthesize nanoparticles by using Pistacia chinensis extract and directed the researcher to purify active phytochemicals from Pistacia chinensis involved in nanoparticles synthesized.

“…FTIR spectra of plant extract is shown in figure 6(c). The presence of vibrational band within the range of 1300-1700 cm −1 was due to the functional groups of proteins i.e., C=O, −C−N, which resulted in the formation of the amide bands [46]. Similarly, the Alcohols and phenols produce characteristic infrared bands due to O-H stretching and C-O stretching in the regions around 1000 cm −1 , whereas, presence of -NH or moisture causes similar results [47].…”

Herein, we prepared the zinc oxide (ZnO) and silver doped zinc oxide (Ag-ZnO) nanoparticles (NPs) using Berberis aristata plant extract as a reducing, capping and stabilizing agent. The x-ray diffraction (XRD) pattern confirms the formation of pure hexagonal wurtzite structure for both the samples with P4mm space group. The crystallite size reduces from 21.313 nm to 18.179 nm with the Scherrer technique with doping of Ag ions on ZnO NPs, while the Williamson Hall (WH) approach likewise demonstrates a decrease in crystallite size from 26.602 nm to 21.522 nm. The lattice strain increases from 0.0031 to 0.0064, indicating the presence of Ag-ions in the crystal lattice of ZnO NPs. For both samples, the metal-oxygen bond formation is supported by the Fourier Transform Infrared (FTIR) spectra. For ZnO, the peak in the UV-visible spectrum is approximately around 365 nm, but for Ag-ZnO, two peaks are observed around 235 nm and 360 nm. With the Ag doping, the bandgap increases from 3.01 eV to 3.02 eV. Transmission Electron Microscopy (TEM) micrographs show the formation of crystalline particles and Field Emission Scanning Electron Microscopy (FESEM) pictures show the formation of aggregated NPs with a spherical shape. Energy Dispersive x-ray Spectroscopy (EDX) and x-ray Photoelectron Spectroscopy (XPS) demonstrate the chemical purity of both the samples. The antibacterial activity of ZnO NPs was highest against Staphylococcus aureus i.e., 15 ± 0.53 mm, whereas, for Ag-ZnO NPs the highest activity was against Salmonella typhi i.e., 19 ± 0.53 mm.
