عنوان انگلیسی Synthesis of NiO Nanoparticles and Sulfur, and Nitrogen co Doped-Graphene Quantum Dots/ NiO Nanocomposites for Antibacterial Application
چکیده انگلیسی مقاله The human life is faced with bacterial infections which are one of the major cause of prevalence and mortality. Antibiotics have long been the preferred therapy for bacterial infections due to their cost-effectiveness and efficacy. In the field of overcoming microbial issues, new and emerging nanostructure-based materials have gotten a lot of attention. In this Study, NiO and sulfur, and nitrogen co doped-graphene quantum dots-decorated NiO nanocomposites (S,N-GQDs/NiO) are prepared via a simple hydrothermal method. Structural and morphological properties of products are determined via XRD, SEM, UV-Vis, and FTIR analysis. The prepared products are applied for the investigation of antibacterial activity against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and methicillin resistant Staphylococcus aureus (MRSA). The results showed that prepared S,N-GQDs/NiO nanocomposites have high antibacterial activity against Staphylococcus aureus among a wide range of microorganisms. For S,N-GQDs/NiO nanocomposites nanoparticles, the disk diffusion test proved that the highest growth inhibition zone was related to Staphylococcus aureus (17 mm). The presence of graphene quantum dots in S,N-GQDs/NiO nanocomposites facilitates reactive oxygen species (ROS) mechanism which lead to bet antibacterial activity.
