Development of corrosion resistant biomedical devices
Lead Beneficiary: UNIUD
Involved Partners: ETHZ, AGH, INEB, LIMA, UNIUD, JSI, TUD, UNITN, MAG
Objectives: Development of corrosion resistant biomedical devices, including implantable micro- and nanoelectrodes for recording or stimulating neuronal activity, prosthesis implants with functionalized micro- and nanofeatured surfaces to promote osteogenesis and microrobotic magnetic implants for drug delivery. The corrosion mechanisms studies feedback will be used to improve the devices design in terms of materials selection, integrative manufacturing and shapes. Protective coatings with multifunctional properties such as corrosion resistance, biocompatibility and antibacterial properties developed during the project will be applied on selected devices. ALD and sol gel coatings with antibacterial properties will be applied on trabecular titanium (microporous) implants in order to enhance the corrosion resistance and reduce the infection risk. Chitosan and polypyrole micro- and nanostructured coatings will be applied on magnesium alloy-based implants in order to increase their corrosion resistance.
