US researchers create new ‘silk’ composite for bone repair

Researchers at the University of Connecticut (UConn) in the US have used silk fibres to develop a biodegradable composite for the repair of load-bearing bones.

Led by UConn professor Mei Wei, the team used the silk fibroin protein present in fibres spun by spiders and moths for their new composite. The protein is tough and features tensile strength.

It is generally used in medical sutures and tissue engineering for its strength and biodegradable nature.
