ABSTRACTThe antibacterial activity of nanosilver against Gram negative Escherichia coli bacteria is investigated by immobilizing nanosilver on nanostructured silica particles and closely controlling Ag content and size. These Ag/SiO2 nanoparticles were characterized by S/TEM, EDX spectroscopy, X-ray diffraction. The antibacterical activity of these composite samples was investigated for a constant composite particle concentration. The highest activity was observed for the higher silver content particles.
