Abstract: | In the case of using polyethyleneimine, the produced nanoparticles showed a homogenous spherical structure. Meanwhile, in the case of using polyvinylpyrrolidone and chitosan, the produced nanoparticles experience non-homogenous morphology with great diversity. Transmission electron microscopy (TEM) and UV-visible spectrophotometry (UV-vis) techniques were employed to study the criteria of the obtained gold nanoparticles. It was obviously concluded that the type and concentration of the reducing agents that were added during gold preparation and acted as stabilizer templates affect to a great extent the morphology and particle shape. Also, stabilizers affect the homogeneity of the produced gold nanoparticles. In the case of using polyethyleneimine, the produced nanoparticles showed a homogenous spherical structure. Meanwhile, in the case of polyvinylpyrrolidone and chitosan, the produced nanoparticles experience non-homogenous morphology with great diversity. |
