- چکیده انگلیسی: In the current work, nickel oxide (NiO) and copper-doped nickel oxide (Cu-NiO) nanoparticles were prepared by co-precipitation method. The effect of Cu doping on the structural and optical features of NiO nanoparticles and the effect of solvent and temperature on the optical and structural properties of nickel oxide and Cu-doped nickel oxide nanoparticles were studided by X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, fourier transform-infrared (FT-IR) spectroscopy and vibrating-sample magnetometer (VSM) technique. The XRD analysis condirmed that the Cu-doped nickel oxide have a cubical structure and showed that the crystalline size increased with the increase of temperature. The optical absorption spectra of the structures illusterated a blue-shift with decreasing in crystal size so that the energy gap of nickel oxide decreased with increasing temperature. Subsequently, in the presence of propranol and without ethylene glycol, the Cu-doped NiO band gap was the lowest and with the applying of ethanol and ethylene glycol was the highest amount. Magnetization property study of the nanoparticles performed at room temperature confirmed the weak ferromagnetic behavior of Cu-doped NiO nanoparticles before calcinations. The magnetization in the magnetic hysteresis loop indicated that nanoparticles have super paramagnetic property after calcination.

- چکیده:
- چکیده انگلیسی: Gold metallic nanoparticles have received a great and well-deserved attention due to their wide application in different fields of scientific and technology, especially biological and therapeutic applications such as cancer diagnosis and treatment according to their advantages including biocompatibility, low toxicity, controlling size and shape, easy synthesis, selective accumulation in cancer cells, high activity, and optical properties. The targeted nanocarriers have given new hope in order to the treatment of this disease all over the world. Understanding the medical effects of gold nanoparticles is a key issue for their rational and efficient design. Regarding this issue, the reported studies indicate that the quality of therapy and identification process of diseases has improved according to gold nanoparticles. It is expected that in the near future, these nanomaterials will provide the most fruitful therapeutic results. With this in mind, this mini-review tries to address new targets for cancer cells, new ways to target based on gold nanoparticles as well as stabilizing nanoparticles locally on cancer cells and the resulting degradation of side effects.
