ABSTRACT: The preparation of stable, uniformed silver nanoparticles by the reduction of silver ions using albumin is reported in the present paper. It is a simple process for obtaining silver nanoparticles. The samples have been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM), which reveal the nature of the nanoparticles. These studies conclude that the particles are mostly spherical in shape and have an average size of 26 nm. The UV-vis spectra show that an absorption band, occurred because of the Surface Plasmon Resonance, existing at 443 nm; the Thermogravimetric Analysis (TGA) shows that only 2% of the weight is organic matter. The average particle size was measured with a Nanosizer DLS.
