Nanotechnology has become commonplace in the field of medicine in today’s world. On one side, there are targeted drug delivery techniques that use nanomaterials, and nano-sized robots that wander inside our bodies. On the other, there is an evolving application of nanomaterials focused on prosthetic metal implants.

When one suffers from fractures or needs prosthetic implants, the process of osseointegration — where the bone is integrated with titanium implants — is followed. An emerging area of research is the application of nanomaterials on these implants.

In a recent study, researchers from the Indian Institute of Technology Bombay, Tata Memorial Centre and Advanced Centre for Treatment, Research and Education in Cancer, Mumbai, have used such metallic implants coated with nanofibres that enhance the formation and growth of new bone tissue on the surface compared to implants without the coating. The preclinical study, tested on rabbits, was published in Tissue Engineering and Regenerative Medicine.
