Biopolymer chitosan nanocomposites have been synthesized using chitosan nanoparticles with the addition of montmorillonite. Here montmorillonite (MMT) acts as a nanofiller and diluted acetic acid is used as a solvent for dissolving chitosan and dispersing montmorillonite with chitosan nanoparticles. Morphology and properties of chitosan nanocomposites with and without acetic acid residue have been studied compared with those of pure chitosan. The effect of the acetic acid residue of chitosan and MMT loading in nanocomposites has been investigated. The characterization shows that the XRD Spectrum deceived that the crystallinity of the synthesized chitosan nanocomposite. FTIR spectrum revealed that the presence of elements in chitosan nanocomposites. The surface morphology of chitosan nanocomposites that were solid shaped was determined by SEM analysis, and the presence of silica and oxygen were confirmed by EDAX analysis. These prepared chitosan nanocomposites have been characterized by X‐ray diffraction (XRD), Scanning electron microscopy (SEM-EDAX), Ultra Violet Spectroscopy (UV), Fourier Transform Infrared Spectroscopy (FTIR), and Particle Size Analyser (PSA). The antibacterial activity of Chitosan nanocomposite shows that the antibacterial zone of inhibition between 0.9 to 1.5mm at the concentration of 10, 20, 40, 80µl against Pseudomonas, Enterobacter, Bacillus.

During the last decade green synthesized cerium oxide nanoparticles (CeO2 NPs) attracted remarkable interest in various fields of science and technology. Cerium oxide nanoparticles have been used in a number of non-medical products over the years. Synthesis of cerium oxide (CeO2) nanoparticles was studied by new and simple co-precipitation method. The crystalline structure, surface morphology, phases, functional groups and size were examined by assorted characterization techniques like scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Thermo gravimetric analysis (TGA) and fluorescence spectroscopy studied were investigated. Furthermore, the antibacterial properties of CeO2 nanoparticles were investigated by their bacterial activity against four bacterial strains using the agar well diffusion method.
