This is the outcome of intense research and it involves the method for preparing nanostructured calcium silicate as drug deliver agent The capacity of this drug delivery agent is higher than that of commercial drug delivery agents. The research involves the preparation" of nanosized calcium silicate and subsequent mixing of desired chemotheropic agent including antibiotics at the level of human tolerated dose of respective antibiotics. This is essential in the treatment of fractured bones, degenerated bones, bone deformities, degenerated spines, dental corrosion and disorders.
