Abstract
Excellent characteristics and a wide range of applications made nanotechnology a key focus for modern researchers. However, environment-friendly and cost-effective measures still need to be taken to synthesize nanoparticles. This research focused on synthesizing Green Ceramic-based Nanoparticles (GCNPs) using the sol-gel method. This method is environment-friendly and cost-effective. Different analytical techniques were employed to characterize the obtained GCNPs. Crystallographic parameters were obtained through the X-ray diffraction (XRD) analysis. Morphological analysis was performed by Field Emission Scanning Electron Microscope (FESEM) analysis. The presence of different elements was identified by elemental analysis (EDX). Various functional groups present in the GCNPs were identified by Fourier Fourier-transformed infrared Spectroscopy (FTIR) analysis. XPS and zeta potential analyses composition characterization and surface charge stability, respectively. Antibacterial strains against E. coli were performed. The FTIR analysis confirmed the presence of different organic compounds in the synthesized GCNPs which helped to increase bacterial inhibition in the antibacterial test. The FESEM images confirmed irregularity in the shape and aggregation of the synthesized GCNPs. The minimum average particle size was obtained from sample S2 which is 376.35 nm. EDX analysis confirmed the presence of silicon particles in the GCNPs. The crystalline nature of the GCNPs was assured by XRD analysis. The silicon percentages were higher than the other atoms shown by the XPS analysis. A significant amount of bacterial inhibition which was 18.0 mm obtained from sample S3. Finally, GCNPs were prepared, characterised, and significantly applied for diverse implementation for the safety of the healthcare field on a broad scale.
