Abstract
Skin is uniquely accessible to investigation by modern scientific methods. Raman spectroscopy is a non-invasive technology for in-vivo analysis of molecular composition. Furthermore, a skin biopsy examined with Laser ablation - Inductively Coupled Plasma - Mass Spectrometry (LA-ICP-MS) provides high resolution multi-element mapping with high sensitivity and precision for exogenous metals in biological tissue which have no intrinsic abundance. This technique has been successfully applied to identify a variety of metals including gadolinium in cerebral vessel walls after contrast studies (1) . These two techniques were used to investigate metallosis from a shoulder joint replacement.
