Bones to be grown with Nanotechnology

If everything goes well then soon the medical fraternity will be able to replicate bones. A new nanoscale biocomposite has been developed by scientists in Singapore which will help in mimicking the extracellular matrix architecture. For this purpose electrospinning technique was used for fabricating polycaprolactone/nanohydroxyapatite/collagen biocomposite nanofibrous scaffolds which would offer mechanical support and lead to the growth of human fetal osteoblasts. This scaffold would be offering structural integrity within the body and ultimately breakdown leaving behind the neotissue which will be instrumental in repairing the diseased tissues and organs. Venugopal, Researcher, Nanoscience and Nanotechnology Initiative said: The resulting nanofibrous scaffolds were highly porous (>80%) structures and provided a sufficient open pore structure for cell occupancy whilst allowing free transport of nutrients and metabolic waste products. Moreover, vascular in-growth was facilitated. The mineralization was significantly increased (55%) after 10 days of culture and appeared as minerals synthesized by osteoblast cells
