Investigations of mechanically enhanced metal-ion release from biomaterials by means of radiotracer technique, Final Scientific Report
The present report presents the experiments and results obtained during the Marie-Curie Individual Fellowship MCFI-2000-01457 �Investigations of mechanically enhanced metal-ion release from biomaterials by means of radiotracer technique�. The idea of the project was to use a highly sensitive technique - namely Thin Layer Activation (TLA) - in order to quantitatively measure the material released in specific damage mechanisms as they may occur in modern modular medical implants. With the highly sensitive technique TLA it is possible to run experiments under �low loading�, meaning frequencies between 1 Hz to 10 Hz and with cyclic axial loads as the occur in the human body. During the 24 months of the project a testing device was set up and the PC control and data acquisition realized. The project was focused on establishing the technique. Four sets of experiments using TLA could be conducted and it was demonstrated that it is possible to measure wear volumes in the nano gram-range, which is possible with controversial weighing techniques.
