Investigating Mg Biocorrosion In Vitro: Lessons Learned and Recommendations

Magnesium (Mg) alloys are achieving good clinical success in applications as temporary biodegradable medical implants. However, the study of the corrosion in medical environments (biocorrosion) is still ongoing. Much of this study is conducted via laboratory (i.e., in vitro) immersion tests, which can be challenging. We have outlined and updated a range of recommendations on the in vitro biocorrosion assessment of Mg alloys, based on our experience in the field and the lessons learned through years of experiments. We hope these recommendations will help to improve future biocorrosion testing and provide insight for both researchers with experience in this field and those seeking to enter it.
