Schematic representation of the main pathways underlying the antibacterial potential of the rGO/Ni-BDP NPs: (I) Adheres of rGO/Ni-BDP NPs to and wrap the bacterial cell surface, resulting in damage of bacterial cell. (II) rGO/Ni-BDP NPs penetrate the microbial cells and affect the respective cellular machinery. (III) rGO/Ni-BDP NPs creates and increases ROS, leading to cell damage. (IV) rGO/Ni-BDP NPs modulates the cellular signal system and causing cell death. (V) Finally, rGO/Ni-BDP NPs block the ion transport from and to the microbial cells.
