ARCI, SCTIMST jointly develops biodegradable metal implants

ARCI, SCTIMST jointly develops biodegradable metal implants

Saturday 16th May 2020

Scientists at the International Advanced Research Centre for Powder Metallurgy and New Materials, ARCI and Sree Chitra Tirunal Institute of Medical Sciences, Thiruvananthapuram have jointly developed new generation Iron-Manganese based alloys for biodegradable metal implants for use in humans. 

Biodegradable materials (Fe, Mg, Zn, and polymer), which can participate in the healing process and then degrade gradually by maintaining the mechanical integrity without leaving any implant residues in the human body are better alternatives to currently used metallic implants which remain permanently in the human body and can cause long-term side effects like systemic toxicity, chronic inflammation, and thrombosis.

During the degradation process, calcium phosphate deposits on the implant due to local alkalization and saturation of calcium and phosphate, allow cells to adhere onto the surface to form tissues.
