Nowadays, zinc oxide nanoparticles (ZnO NPs) have been shown to exhibit potent antibacterial activity against a wide range of pathogenic bacteria. Numerous investigations delved into exploring the activities exhibited by ZnO NPs. Notwithstanding, correlation between morphology these and their resultant impacts remains an area demanding further exploration across varying morphological variations. This paper presents comparative study on how affects efficacy. In this regard, NPs with different morphologies, including spherical, rod-like, flower-like structures, were synthesized via modified precipitation method characterized using X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), field emission scanning electron microscopy (FE-SEM), dynamic light scattering (DLS), Brunauer–Emmett–Teller (BET) analysis, reactive oxygen species (ROS) techniques. The was evaluated Gram-positive bacterium (Staphylococcus aureus) two Gram-negative bacteria (Escherichia coli Pseudomonas aeruginosa) through disk diffusion, minimum inhibitory concentration (MIC), bactericidal (MBC) tests, cytotoxicity assessed MTT assay. results showed that rod-like highest both Conversely, spherical displayed lowest activity. Remarkably, assessments exerted toxicity toward HepG2 human dermal fibroblasts (HDF) cells, whereas demonstrated least cytotoxic effects. extent cell membrane damage determined measuring DNA RNA leakage, visual confirmation FESEM imaging. provide valuable insights relationship nanoparticle efficacy, shedding mechanisms underlying superior morphology. Overall, findings designing developing efficient agents minimal adverse effects, opening up avenues for future research in nanomedicine biomedical applications.

Chemistry - A European Journal, Journal Year: 2024, Volume and Issue: 30(24)

Published: Jan. 31, 2024

Surface-enhanced Raman scattering (SERS) spectroscopy, a highly sensitive technique for detecting trace-level analytes, relies on plasmonic substrates. The choice of substrate, its morphology, and the excitation wavelength are crucial in SERS applications. To address advanced requirements, design use efficient nanocomposite substrates have become increasingly important. Notably, magnetic-plasmonic (MP) nanocomposites, which combine magnetic properties within single particle system, stand out as promising nanoarchitectures with versatile applications nanomedicine spectroscopy. In this review, we present an overview MP fabrication methods, explore surface functionalization strategies, evaluate their SERS.

Antioxidant and Anti-inflammatory Applications of Aerva persica Aqueous-Root Extract-Mediated Synthesis of ZnO Nanoparticles

ACS Omega, Journal Year: 2024, Volume and Issue: 9(14), P. 15882 - 15892

Published: March 29, 2024

In the present study, ZnO nanoparticles were synthesized by using aqueous extracts of Aerva persica roots. Characterization as-prepared was carried out different techniques, including powder X-ray diffraction (XRD), UV–vis diffuse reflectance spectroscopy (DRS), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscopy (FESEM), transmission (TEM) and BET surface area analysis. Morphological analysis confirmed small, aggregated flake-shaped morphology as-synthesized nanostructures. The analyzed for their potential application as anti-inflammatory (using in vivo inhibition carrageenan induced paw edema) antioxidant vitro radical scavenging activity) agents. found to have a potent activity comparable that standard ascorbic acid (antioxidant) indomethacin (anti-inflammatory drug). Therefore, due ecofriendly synthesis, nontoxicity, biocompatible nature, zinc oxide successfully from roots extract plant with efficiencies can be utilized biomedical applications.
