Scanning electron microscope images showed that the untreated control groups ( A , C , E , G ), bacterial cells exhibited normal morphology with intact cell walls and smooth surfaces. In contrast, treated cells ( B , D , F , H ) showed significant morphological changes: S. aureus cells displayed shrinkage and deformations in their spherical shape, while E. coli cells exhibited marked structural disintegration and severe membrane damage. These observations confirm the destructive effects of silver nanoparticles on bacterial cell integrity. Most of the cells were damaged and perforated, which changed the cell structure and shape, and it was noted that some of them were empty. In addition, most cells appeared to stick together compared to untreated cells. As is clear in .
