Structures, morphological control, and antibacterial activity of silver-titanium dioxide (Ag/TiO 2 ) micro-nanocomposite materials against Staphylococcus aureus are investigated in this study. Horizontal vapor phase growth (HVPG) technique was used to synthesize the Ag/TiO 2 micro-nanomaterials, with parameters of growth temperature and baking time. The materials were characterized by using scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, and atomic force microscope (AFM). The result indicated that the HVPG technique is able to synthesize Ag/TiO 2 with many shapes in micro- and nanoscale such as nanoparticles, nanorods, triangular nanomaterials, and nanotubes. The results showed that the shape of micro- and nanocomposites material could be arranged by adjusting the parameters. The results revealed that the nanorods structure were obtained at 1000°C growth temperature and that 8 hours of baking time was ideal for antibacterial application. Treating the S. aureus stock with Ag/TiO 2 nanocomposites is able to reduce bacterial growth with a significant result.
