Electrochemical impedance response of the nanostructured Ti–6Al–4V surface in the presence of S. aureus and E. coli

Popis výsledku v původním jazyce

Implant infections associated with biofilm are a significant problem in current healthcare. Early detection of the development of bacterial infection would allow the deployment of antibiotic treatment to suppress complications. Biofilm detection can be based on the changes in the electrochemical response of a metal oxide sensor. The nanostructured surface of titanium alloys provides a large active/geometric surface area ratio and may respond to the presence of bacteria by changing its behaviour. In this work, the changes in impedance response of nanostructured Ti–6Al–4V alloy surface in the presence of E. coli and S. aureus were studied. The nanostructures were prepared by anodic oxidation in a fluoride ions-containing environment. The change in impedance spectra and open circuit potential of the prepared surfaces was monitored for 48 h. Furthermore, a series of measurements in model systems were carried out to help identify the processes leading to the change in the electrochemical behaviour of the surface. The measurements showed significant changes in the surface impedance response over a wide range of frequencies and for both bacterial strains. Based on the results, the implantable sensor based on the nanotubular titanium oxide seems to be a possible and simple way how to detect bacterial infection.
