[PMID: 38877835 DOI: 10.1002/jemt.24630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2024] [Revised: 05/18/2024] [Accepted: 05/30/2024] [Indexed: 06/16/2024]
Abstract
One of the most important areas of nanotechnology is the use of nanoparticles (NPs) for a variety of environmental and biological applications, with silver nanoparticles (Ag-NPs) gaining a lot attention due to their distinct properties. The current study deals with the synthesis of Ag-NPs from Dicliptera bupleuroides Nees leaf extract and to determine their antioxidant, antimicrobial potential and effects on wheat seed germination and growth. UV-Visible spectrum revealed a prominent absorption peak at 442 nm, elucidating the conformation of the Ag-NPs synthesis. Scanning electron microscopy (SEM) showed distinctive triangular, pyramidal, and irregular shape. X-ray diffraction (XRD) demonstrated their crystalline nature, with average crystallite size of the Ag-NPs measured at 20.52 nm. Fourier-transform infrared spectroscopy (FT-IR) further confirmed the presence of functional groups such as Phenols (O-H stretch), transition metal carbonyls N-H, ≡C-H, C ≡ N, C ≡ C, C-Cl, C-Br and O-H bonds on the surface Ag-NPs. The antibacterial activity of the Ag-NPs was most pronounced against Bacillus subtilis, with a zone of inhibition (ZOI) measuring 11 mm ± 0.57 at a concentration of 1000 μg/mL (45% inhibition). Likewise, Ag-NPs exhibited highest antioxidant potential (73.2%) at 100 μg/mL compared with standard (ascorbic acid) which showed (76%) at the same concentration. Furthermore, the effect of D. bupleuroides mediated Ag-NPs on wheat seeds growth and germination was recorded maximum at high concentrations (200-300 ppm). In conclusion, D. bupleuroides mediated Ag-NPs showed safe, cost effective and environmentally friendly synthesis which can be used as an antibacterial and antioxidant agent as well as for enhancing the growth and seed germination of crop seeds globally. RESEARCH HIGHLIGHTS: Nanotechnology is the study of nanoparticles for biological and environmental applications. Ag-NPs among other NPs have received broad attention because of their unique properties. D. bupleuroides Ag-NPs: 45% antibacterial, 73.2% antioxidant, enhance wheat germination. D. bupleuroides-mediated Ag-NPs are both cost-effective and environmentally beneficial.

[PMID: 38293495 PMCID: PMC10824772 DOI: 10.1016/j.heliyon.2024.e24303] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 01/04/2024] [Accepted: 01/05/2024] [Indexed: 02/01/2024] Open
Abstract
Extracts obtained from M. longifolia (Lamiaceae) and R. ellipticus (Rosaceae) were selected to utilize in the reduction and stabilization of silver nanoparticles (AgNPs) for achieving remarkable bioactivities. In brief, the cytotoxic potential of the as synthesize AgNPs was high at higher concentrations. In DPPH assay, maximum antioxidant potential was shown by AgNPs synthesized from M. longifolia. Meanwhile, Methanolic extracts exhibited more antioxidant potential than chloroform based extracts. Further, brine shrimp lethality assay was carried out to achieve 34.6 μg/mL & 25.65 μg/mL LD50 values against the NPs prepared from M. and R., respectively. In addition, antioxidant activities were carried by ABTS Radical cation assay where 38.6 μg/mL and 47 μg/mL IC50 values were obtained for the NPs obtained from M. longifolia and R. ellipticus, respectively. Reducing power assay (0.370-0.15 and 0.37-0.26 mean absorbance) and DPPH (% scavenging: 88.91-46.48 and 88.91-44.78) percentages were recorded for M. and R. synthesized AgNPs, respectively. In brief, M. longifolia functionalized particles performed better in comparison to R. ellipticus treated particles. In addition, the nano assembly dispersed in polar solvent demonstrated better results in comparison to non-polar solvents. In conclusion, the as synthesized AgNPs were better in bioactivities than crude extracts of the selected plants. In future, this work could be extended to isolating active components for the nanofabrication of biologically intelligent nanoparticles for pharmacological interest. In the proposed investigation, the purified bioactivities fractions would be highlighted for further consideration in various medical treatments.

Synthesis and Characterization of Zinc Oxide Nanoparticles at Different pH Values from Clinopodium vulgare L. and Their Assessment as an Antimicrobial Agent and Biomedical Application. MICROMACHINES 2023; 14:1285. [PMID: 37512596 PMCID: PMC10383690 DOI: 10.3390/mi14071285] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 06/15/2023] [Accepted: 06/19/2023] [Indexed: 07/30/2023]
Abstract
The current study attempts to evaluate the formation, morphology, and physico-chemical properties of zinc oxide nanoparticles (ZnO NPs) synthesized from Clinopodium vulgare extract at different pH values and to investigate their antimicrobial and biomedical application potential. The reduction of zinc ions to ZnO NPs was determined by UV spectra, which revealed absorption peaks at 390 nm at pH 5 and 348 nm at pH 9, respectively. The spherical morphology of the nanoparticles was observed using scanning electron microscopy (SEM), and the size was 47 nm for pH 5 and 45 nm for pH 9. Fourier-transformed infrared spectroscopy (FTIR) was used to reveal the presence of functional groups on the surface of nanoparticles. The antibacterial activity was examined against Staphylococcus aureus, Streptococcus pyogenes, and Klebsiella pneumonia via the agar-well diffusion method. Comparatively, the highest activities were recorded at pH 9 against all bacterial strains, and among these, biogenic ZnO NPs displayed the maximum inhibition zone (i.e., 20.88 ± 0.79 mm) against S. aureus. ZnO NPs prepared at pH 9 exhibited the highest antifungal activity of 80% at 25 mg/mL and antileishmanial activity of 82% at 400 mg/mL. Altogether, ZnO NPs synthesized at pH 9 show promising antimicrobial potential and could be used for biomedical applications.
