nanoXIM HAp powders are micrometric aggregates of hydroxyapatite nanoparticles.
These products are used in the manufacturing of bone graft substitutes, such as porous granules and blocks scaffolds for bone regeneration.
Due to the similarity between nano-hydroxyapatite and mineralized bone, nanoXIM HAp powders have a high affinity to hard tissues as they form chemical bonds with the host tissue resulting in an improved biological performance.
|Promotes fast bone regeneration and an early vascularization due to their osteoconductive and osteostimulative properties|
|Encourages protein adsorption and osteoblast adhesion|
|Enhances osteoblast functions|
|Resorbable material replaced by new bone during the healing process|
|Narrow particle size distribution|
|Nanostructured micron sized powder|
|High surface area (≥100 m2/g)|
nanoXIM•HAp200 is a series of nanostructured synthetic hydroxyapatite powders, manufactured and supplied in two different particle sizes, 5 and 10 μm.
This feature is achieved in the drying process by spray dryer technique where the nanoparticles in liquid phase are dried as spherical aggregates with a high surface area.

The formation of a stable microvasculature is an essential process to ensure a successful regeneration of bone tissue.
The viability and proliferation of bone cells are essential during bone regeneration. In this study, it was evaluated the viability and proliferation of MG63 cells (osteoblast-like cells) cultured on substrates produced with nanoXIM•HAp202, in comparison with the ones produced with micro HAp.
