Carbon nanotube-based biomaterials for orthopaedic applications

Area of Science:

• Biomaterials Science
• Nanotechnology
• Orthopedic Surgery

Background:

• Carbon nanotubes (CNTs) are advanced carbon nanomaterials with exceptional mechanical, electrical, and thermal properties.
• CNTs are being explored as high-performance biomaterials for orthopedic applications, offering enhanced durability and function.
• Concerns exist regarding CNTs' potential carcinogenicity, similar to asbestos, necessitating careful biocompatibility and safety evaluations.

Purpose of the Study:

• To review the clinical applications of carbon nanotubes in orthopedic surgery.
• To examine the biocompatibility and carcinogenicity of CNTs, focusing on their effects on bone, joints, and the respiratory system.
• To introduce various CNT-based biomaterials developed for orthopedic applications.

Main Methods:

• Literature review of studies on CNT biocompatibility and carcinogenicity.
• Analysis of research on CNTs' effects on orthopedic tissues and the respiratory system.
• Compilation of reported CNT-based biomaterials for bone/cartilage regeneration, composite enhancement, coatings, and tumor treatment devices.

Main Results:

• CNTs exhibit promising properties for orthopedic applications but raise safety concerns due to potential carcinogenicity.
• Biocompatibility and carcinogenicity studies indicate varied effects on bone, joint, and respiratory systems.
• Various CNT-based materials, including scaffolds, composites, coatings, and therapeutic devices, have been developed.

Conclusions:
