▎ 摘　　要

Herein, the novel chitosan-graphene oxide/tin oxide (CS-GO/SnO2) hybrid composites were derived by one-pot reaction. The different SnO2 and GO percentages were used to blend with chitosan to structuralize the CS-GO/SnO2 nanocomposites. CS-GO and CS-GO/SnO2 hybrid formation were structurally ascertained by Fourier-transform infrared spectral studies. X-ray diffraction outcomes evidently proved the formation of amorphous CS-GO and semicrystalline CS-GO/SnO2 hybrids. Surface properties variations extensively conferred with scanning electron micrographs for CS-GO and CS-GO/SnO2. The antibacterial performance of CS-GO and CS-GO/SnO2 were established in terms of zone of inhibition against different microorganisms such as Salmonella typhi, Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis.
