The presence of –CO, –CHO, and –OH groups renders the easy functionalization of GO by biomolecules and drugs. Therefore, in this study, we designed a multifunctional GO–Fe3O4 nanocomposite and investigated its bactericidal activity against different bacterial strains with an evaluation of percentage inhibition. Our results revealed the potential of GO–Fe3O4 nanocomposites as an effective bactericidal, which can be used for dynamic applications in medical devices and food and other industries.
