Bacterial infections are a rising concern, and nanomaterials offer promising solutions to combat them. The synthesis and antibacterial characteristics of zinc sulfide/chitosan nanocomposite were investigated to solve this critical issue, paving the way for new possibilities in this filed. The manufacturing and analysis of these nanocomposites were also studied based on some imaging methods such as XRD, FTIR, FESEM, EDX elemental mapping, and antibacterial (a colony count method). The results from XRD indicated that chitosan and hexagonal ZnS crystals with the average size of 30-40 nm formed ZnS/CS nanoparticles. The FTIR spectrum revealed nanoparticle groups and bonding which were indicative of synthesis and stability. Additionally, FESEM imaging demonstrated the surface shape of the nanocomposite with a particle size distribution of 212-nm, and EDX confirmed its components and composition. Antibacterial effectiveness against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria was also evaluated. ZnS nanoparticles and ZnS/CS nanocomposite were found to be more potent than CS and ZnS alone. These findings show that the produced samples may provide insights into prospective paths for fighting bacterial infections and enhancing biomedical technologies.
