Bio-Inspired Coating for 3D-Printed Bone Implants

Recently, researchers from IIT Mandi developed a bio-inspired surface coating for 3D-printed bone implants that could mechanically disrupt bacteria and improve implant integration with bones.

Key Points

Bio-Inspired Coating: The coating uses tiny hydroxyapatite structures resembling sea urchins on biodegradable plastic scaffolds.
Dual Benefits: The technology addresses bacterial infections and poor integration of implants with bones.
Hydroxyapatite: It is a major mineral component of human bones and supports bone-compatible mineralisation.
3D-Printed Scaffold: Researchers used polylactic acid (PLA), a biodegradable polymer that can be customised for individual bone defects.
Bacterial Disruption: The needle-like structures can mechanically damage bacteria and reduce bacterial colonisation without antibiotics.
