Transmission electron microscopy (TEM) images display the prepared nanoparticles, including O.CS nanoparticles shown in both an overall view (A) and –ve window view (a), SiO2-CS nanoparticles displayed in an overall view (B) and –ve window (depicting images with reverse grayscale) to observe a close-up view (b), SiO2 nanoparticles (C), and Fe3O4 nanoparticles (D) and a close-up view. (E–H) The morphology of the synthesized samples was confirmed by SEM analysis.
