چکیده

The external and interlamellar spaces of MMT were used as solid support for synthesis of CuO NPs at room temperature by the chemical reduction method. In this project, Copper Nitrate (Cu(NO₃)2. xH(2)O) and Sodium Hydroxide (NaOH) were used as Copper precursor and reducing agent respectively. Then, MMT/Cu⁺ nanocomposites were stabilized with different range of the weight percent of Polyethylene glycol (PEG). The solids were characterized by X-Ray diffractometry (XRD), Scanning electron microscopy (SEM)‚ Transmission electron microscopy (TEM)‚ Fourier transform infrared (FT-IR) and UV-Visible spectroscopy. The antibacterial activities of different sizes of CuO NPs in MMT were investigated against Gram-positive‚ Staphylococcus aureus and Gram-negative bacteria‚ Escherichia coli‚ by the disk diffusion method using Muller-Hinton agar (MHA). These results were showed that CuO NPs were found to have high antibacterial activities. By this method we were able to obtain CuO NPs with different sizes and making them applicable to medical applications and can be used as effective growth inhibitors in different biological system.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
