Researchers from Indian Institute of Technology (IIT) Hyderabad and Dr.B.R. Ambedkar National Institute of Technology (NIT) Jalandhar have developed a process by which bone implant materials can be synthesized from waste eggshells.
- Bone graft is a surgical procedure to fix problems with bones or joints. Bone grafting, or transplanting of bone tissue, is beneficial in fixing bones that are damaged from trauma or problem joints
- The bones are usually fixed using natural body materials or artificial and synthetic materials such as Plaster of Paris, and more recently, phosphate compounds like hydroxyapatite and calcium phosphate but they can be poisonous in some cases.
Features and Importance of research
- Large amount of eggshells are dumped as waste across the world but bioceramics made from them exhibit greater biocompatibility than other synthetic powders due to the presence of additional bioactive elemental ions. Eggshells are inexpensive and can be obtained in unlimited quantities
- Researchers have synthesized Tricalcium phosphate nanopowder which is hundred thousand times smaller than the width of a single human hair from eggshells.
- There is always some hesitancy in using synthetic chemicals as bone replacement materials because of the presence of chemical residues that are toxic if not eliminated completely.
- Materials like ß-tricalcium phosphate (ß-TCP) , processed using nitrate compounds can be dangerous for health and needs urgent substitution.
