Hydroxyapatite is widely used in various fields, including:
1. **Biomedical Applications**:
- **Bone Grafting**: Acts as a scaffold for bone regeneration and repair.
- **Dental Products**: Used in coatings for dental implants and as a component in toothpaste for remineralization.
2. **Bioceramics**:
- Employed in orthopedic and dental implants due to its biocompatibility and similarity to natural bone.
3. **Drug Delivery**:
- Serves as a carrier for delivering drugs, especially in targeted therapy.
4. **Tissue Engineering**:
- Provides a matrix for cell attachment and growth in tissue engineering applications.
5. **Water Treatment**:
- Utilized for adsorbing heavy metals and contaminants in water purification processes.
These applications highlight hydroxyapatite's ultimate role in enhancing health and environmental safety.
