General description
Hydroxyapatite(HAP) is an osteoconductive bioceramic material which has uniqueability to form direct bonds with living tissues. It can be easily prepared byvarious techniques such as sol-gel, hydrothermal, multiple emulsion, biomimeticdeposition, and electrodeposition.
Application
Hydroxyapatite can be used as:
- An implant material for bone substitute due to its chemical similarity to the inorganic component of bone and osteo inductive properties.
- A vehicle for gene and drug delivery because of its encapsulation capacity and affinity to several drugs and proteins.
- A pH responsive particulate emulsifier.
Features and Benefits
- Biocompatible
- Osteoconductive
- Stable under physiological conditions
- High mechanical strength
