Scientists Develop Strong and Flexible Material for Bone Repair

Chinese researchers have created a new material called "nano bone cement", closely mimicking the composition and properties of human bone. It is based on calcium phosphate, citric acid, polyacrylic acid, and L-form polyaspartic acid.

Unlike traditional bone grafts — autografts (patient’s own tissue) and allografts (donor tissue) — this new material is safe, biocompatible, and avoids common complications. Existing synthetic bone materials often lack flexibility and tend to crack, leading to further injury.

Key advantages of the new material:

• Can be shaped freely before hardening, useful for complex bone defects.
• High strength, elasticity, and stiffness.
• Absorbs water after implantation and expands, forming a porous structure that promotes cell attachment.
• Improves comfort and mobility during recovery.

Researchers believe it could become a strong alternative to bone grafts, simplifying surgery and speeding up healing.

The study was published in Nature Communications.
