Abstract: Strontium oxide (SrO) nanoparticle and various concentrations of chitosan (CS)-doped SrO nanocomposite were synthesized via co-precipitation method. A variety of characterization techniques including were done for characterizing and qualifying the nanocomposite. X-ray powder diffraction affirmed cubic and tetragonal structure of SrO nanoparticle and CS-doped SrO nanocomposite with a decrease in crystallinity upon doping. Fourier transform infrared spectrum endorsed existing functional groups on CS/SrO surfaces while d-spacing was estimated using high resolution Transmission electron microscopes images. UV-Visible and Photoluminescence spectroscopy spectra showed an increase in band gap energies with an increase in doping concentration. Elemental composition of CS-doped SrO nanocomposite deposited with different doping concentrations was studied using Energy dispersive Spectroscopy.

Abstract: CS-doped SrO nanocomposite were successfully synthesized through co-precipitation route for bactericidal activities. Effect of CS doping on morphological features, optical properties, elemental composition and phase constitution on CS-doped SrO nanocomposite was analyzed. XRD analysis confirmed tetragonal and cubic structures of SrO nanoparticles and CS-doped SrO nanocomposite. UV-vis spectroscopy was used to obtain 4.19 eV of SrO nanoparticles while emission spectra of doped SrO showed blueshift upon CS doping with multi-concentration. Interlayer d-spacing attained from HRTEM micrographs well matched with XRD d-spacing. Purity content of prepared nanostructures was measured with EDS analysis. Overall, 0.06:1 showed significant antibacterial activity against both Gram +ve and -ve bacterial isolates. Thus, CS-doped SrO nanocomposite can be used in modem medicine as an alternative antibacterial to overcome the development of resistance to antibiotics.
