Resumen
Silver nanoparticles (AgNP's) have been immobilized onto silica spheres through the adsorption and subsequent reduction of Ag+ ions on the surface by trisodium citrate. The SiO2-Ag0 spheres were characterized by high resolution transmission electron microscopy (HRTEM), UV-Vis diffuse reflectance (DRS), and Fourier Transform Infrared Spectroscopy (FT-IR). Posterior antibacterial tests of the SiO2-Ag0 spheres were done on Staphylococcus aureus (ATCC 6538) and Escherichia coli (ATCC 10536); which showed good performance.
