Synchrotron Infrared Microspectroscopy for Assessment of Mutagenicity of Metal Implants
Published online by Cambridge University Press: 15 February 2011
Abstract
A major concern in the development and implementation of metal implants for the clinical use is the assessment of material-induced mutagenesis. In this study we used synchrotron microspectroscopy in the mid-infrared region (4000-400 cm1 ) to non-invasively assess the in situ human cell responses to metal surfaces. Specifically we examined the subtle genetic aberrations of cells as they responded to a range of metals commonly used in metal prosthetic devices. Relative band intensities and band intensity ratios for functional groups of biomolecules that are inherent to the experimental system were examined. The molecular components of the biomolecules as they were perturbed by the interactions with metals were investigated. These results demonstrate the potential use of synchrotron FTIR microspectroscopy to screen the mutagenicity of metal implants.
