Document Abstract
In this work, we report the synthesis of graphene oxide nanosheets (GO NS) using four
dierent oxidants, namely, chloramine-T (CAT), FeCl3, N-bromosuccinimide (NBS), and KIO3. Fourier
transform infrared spectroscopy (FTIR) was used to characterize the functional groups present in
the synthesized GO. The microstructure analysis was performed using X-ray diraction (XRD)
and scanning electron microscopy (SEM) to investigate the morphology of GO. High-resolution
transmission electron microscopy (HRTEM) studies demonstrated the nanostructure and crystalline
phases of GO. The antibacterial activity of the prepared GO NS was investigated against pure cultures
of Pseudomonas pneumonia and Staphylococcus aureus. The synthesized GO NS with CAT-GO (C-GO)
exhibited very good antibacterial activity towards pathogens.
