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
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.

The scavenger receptor cysteine-rich (SRCR) family of proteins comprises more than 20 membrane-associated and secreted molecules. Characterised by the presence of one or more copies of the ∼110 amino-acid SRCR domain, this class of proteins have widespread functions as antimicrobial

Recombinant human bone morphogenetic protein-2 (rhBMP-2) applied on an absorbable collagen sponge improves open tibial fracture-healing as an adjunct to unreamed intramedullary nail fixation. We evaluated rhBMP-2 and a new, injectable calcium phosphate matrix (CPM) formulation in acute closed tibial

As an alternative to an autologous bone graft, deproteinized bovine bone (DBB) is widely used in the clinical dentistry. Although DBB provides an osteoconductive scaffold, it is not capable of enhancing bone regeneration because it is not osteoinductive. In order

Calcium phosphate precipitates (CPPs) form complexes with DNA, which enter cells via endocytosis. Under this condition CPPs induce autophagy via the canonic autophagy machinery. Here we showed that CPP-induced autophagy was also dependent on endocytosis as the process was significantly

Calcium phosphate ceramics (CPCs) have been widely used as biomaterials for the regeneration of bone tissue because of their ability to induce osteoblastic differentiation in progenitor cells. Despite the progress made towards fabricating CPCs possessing a range of surface features
