heal.abstract	In the present work. composite AgSiO2 thin coatings, containing metal nanoparticles. were prepared on glass substrates by the sol-gel route. The coatings were thermally treated in oxidative and reductive conditions up to 500 degreesC for metal nanoparticle formation, The coating structure and the nanoparticle formation were studied by atomic force microscopy and Rutherford backscattering spectroscopy (RBS) techniques. In the case of RBS, 1.4 MeV He-4(-) ions were used for all samples. and low energy O-16 and C-12 ions in selected ones (heavy ion RBS, HIRBS). in order to improve the depth resolution for the profiling of the metal component. The antibacterial activity against Escherichia coli is examined by antibacterial drop test. The coatings exhibited a high antibacterial activity, which was enhanced with the increase of the metal concentration and was reduced with the increase of the particle size of the metal nanoparticles, The possible correlation between the layer interdiffusion after the thermal treatment and the antibacterial activity is examined and analyzed. Although further studies are required, RBS and HIRBS seem to be excellent tools for the quality control in the production of sol-gel thin coatings. (C) 2002 Elsevier Science B.V.
