The detection of glass particles in glass-induced injuries is often difficult. Most commercial glasses contain iron (Fe3+) centers which present a characteristic electron paramagnetic resonance (EPR) spectrum nearg = 4.3. The detection of small glass particles in vivo can be achieved with low-frequency EPR spectroscopy (1.2 GHz) operating at low field. The method was sucessfully applied in anesthetized live animals where small pieces of glass were implanted under the skin in their backs. This could be a new clinically relevant application of EPR spectroscopy.
