Under the light of current literature (i.e. articles, books, patents and information posted on the nanotech company websites) and the product pipelines of leading pharma/biotech companies, it is evident that we would be seeing many nanotechnology-based pharmaceutical products in this century. It is likely that the oral formulations would dominate this specialized segment of novel dosage forms. The chemical/polymer industry has been feeding the drug delivery scientists with a variety of biopolymers, having wide range of specialized properties. Nanoparticles made from the biopolymers are likely...
