title: Use of microelectrodes as electrochemical sensors of metal ions released from biomaterials.
abstract: In vitro studies to determine Fe3+ levels in mice liver samples were performed using platinum microelectrodes and atomic absorption spectrophotometry. Microelectrodes have been shown to be useful for quantitative analysis of metal ions released during the biodegradation process that occurs on implanted metallic biomaterials.
