Nanomaterials-Upconverted Hydroxyapatite for Bone Tissue Engineering and a Platform for Drug Delivery

Area of Science:

• Biomaterials Science
• Nanotechnology
• Biomedical Engineering

Background:

• Hydroxyapatite is a crucial mineral component of the human skeletal system.
• Synthetic hydroxyapatite (SHA) and its nanocomposites (HANs) are extensively researched for biomedical applications.
• SHA exhibits excellent biocompatibility and osteoconductivity but suffers from poor mechanical strength.

Purpose of the Study:

• To review the reinforcement of SHA with various nanomaterials to form HANs.
• To explore the potential of HANs in bone tissue engineering and drug delivery systems.
• To address the limitations of SHA by enhancing its mechanical properties.

Main Methods:

• Comprehensive literature review on the synthesis and characterization of HANs.
• Analysis of studies incorporating metals, ceramics, and polymers into SHA.
• Evaluation of the impact of different reinforcing agents on HAN properties.

Main Results:

• Incorporation of diverse nanomaterials significantly improves the mechanical properties of SHA.
• HANs demonstrate enhanced performance for bone tissue engineering scaffolds.
• The modified materials show potential for advanced drug loading and delivery systems.

Conclusions:

• HANs offer a promising route to overcome the limitations of pure SHA.
• Tailored HANs can be developed for specific bone tissue engineering and drug delivery applications.
• Further research into HANs can unlock broader clinical and therapeutic uses.
