Silk fibroin coated TiO nanotubes for improved osteogenic property of Ti6Al4V bone implants.

Titanium and its alloys especially Ti6Al4V have long been used in biomedical implants. Although, Ti6Al4V is biocompatible, yet there has been consistent effort to improve its osteoconductive and osteogenic property to enhance the implant performance. In this regard, surface modification of Ti6Al4V implants with TiO nanotubes and subsequent application of biopolymeric coating has started emerging as a promising approach.
