title: [Preparation and anti-bacterial tests of silver-modified titanium surface].
abstract: OBJECTIVE
  To deposit silver nanoparticles on a titanium surface to obtain antibacterial properties. To reduce the incidence of peri-implantitis, and improve the success rate of implantation.
  
  
  METHODS
  A silver nanoparticle-modified titanium (Ti-nAg) surface was prepared using silanization method, and its surface was characterized by using X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectrometer (EDX). Two species of bacteria, namely, Staphylococcus aureus and Escherichia coli, were used to test the antibacterial effect of Ti-nAg surface.
  
  
  RESULTS
  Scanning electron microscope (SEM) revealed that a small quantity of silver nanoparticles were deposited on the titanium surface. XPS analyses revealed that 6.8% of silver was present on the titanium surface. After 24 h of incubation, 94.23% of Staphylococcus aureus and 95.34% of Escherichia coli were killed on the Ti-nAg surface.
  
  
  CONCLUSIONS
  Results suggest that silver nanoparticle-modified titanium is a promising material with an antibacterial property that may be used as an implantable biomaterial.
