Abstract:
A surface coating strategy encompassing the use of bioactive trace elements and reinforcing material will have a significant influence on the mechanical and osseointegration properties of bioceramic coated implants. Here, we developed mineral substituted hydroxyapatite (M-HAP) and carbon nanotube reinforced mineralized hydroxyapatite (CNT/M-HAP) composite coating on titanium (Ti) by pulsed electrodeposition which is a promising approach to produce bioimplants with better osseointegration capacity and improved mechanical properties. The role of CNT and minerals like strontium, magnesium and zinc, in enhancing the mechanical and biological properties of the HAP coating was investigated using various techniques. The structural and morphological analyses were carried out using Fourier transform infrared spectroscopy, X-ray diffraction analysis, scanning electron microscopy, energy dispersive X-ray analysis and elemental mapping. The mechanical characterization results revealed enhanced adhesion strength for the composite coating. Also, an improved viability of osteoblast cells was observed in vitro on the CNT/M-HAP composite coating. The ability of the composite coated Ti implant to induce bone formation was evaluated in vivo in Wistar rats. Thus, the as-developed composite coated Ti that combines the good osteoconductivity of M-HAP together with the mechanical strength of CNT can be used as a potential implant material for orthopedic applications.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
