Iron–Gold Composites for Biodegradable Implants: In Vitro Investigation on Biodegradation and Biomineralization
VPM Rabeeh, SA Rahim… - ACS Biomaterials …, 2023 - ACS Publications
The biocompatibility and biodegradation of iron (Fe) make it a suitable candidate for
developing biodegradable metallic implants. However, the degradation rate of Fe in a
physiological environment is extremely slow and needs to be enhanced to a rate compatible
with tissue growth. Incorporating noble metals improves the Fe degradation rate by forming
galvanic couples. This study incorporated gold (Au) into Fe at very low concentrations of
1.25 and 2.37 μg/g to improve the degradation rate. The electrochemical corrosion test of the …
