Synthesis and Analysis of Nickel Oxide Nanoparticles from Red Hibiscus Plant and Evaluation of Its Antibacterial Properties
Year: 2025
Type: article
Abstract: The presented research examines the environmentally friendly synthesis regarding nickel oxide (NiO) nanoparticles (NPs) for enhancing the properties related to the laser ablation-prepared nanomaterial. Red hibiscus is added as a plant extract to enhance the nanomaterial's properties as well as its antibacterial efficacy. NiO-NPs are created using a Nd: Yag pulsed laser with an 800 mJ wavelength and a wavelength of 1064 nm in a deionized water medium. At room temperature, optical absorbance spectra in the optical range (200-900 nm) have been examined. X-Ray Dispersive Spectroscopy, UV-Vis Spectroscopy, and Scanning Electron Microscopy (SEM) have been used in order to analyze the physical characteristics of NiO-NPs. The formation of high-purity NiO-NPs is demonstrated by EDX analysis. A few NiO-NPs have spherical forms and sizes between 44.66 nm and 134 nm, as seen in the SEM image. NiO-NPs' UV-Vis spectra showed that their absorption edge had a blueshift with an energy gap range (Eg) between 2.80 and 3.40eV. The antibacterial activity regarding NiO-NPs was tested in order to assess their biological efficacy. NiO-NPs were examined in vitro and activated as antibacterials to assess their toxicity. NiO-NPs showed good antibacterial activity against a few of the test organisms.
