Fourier transform infrared microscopic identification of foreign materials in tissue sections.
Fourier-transform infrared microspectroscopy was used to identify polymeric microparticles, such as polyethylene, polysulfone, polytetrafluoroethylene, polyurethane, silicon-based, and nylon-based plastics, in tissue sections. Foreign particles as small as 30 microns in diameter were identified. In addition to being a nondestructive technique, infrared microscopy allows for more precise structural identification of polymeric materials than do X-ray or scanning electron microscopy.
