Nanotechnology and Drug Delivery Part 2: Nanostructures for Drug Delivery
AbstractThis is the second part of a review on nanotechnology in general and particularly as it pertains to drug deliver. In the earlier paper (Part 1), nanotechnology in nature, its history as well as design and methods
were discussed. Its applications, benefits and risks were also outlined. In this paper (Part 2), various nanostructures employed in drug delivery, their methods of fabrication and challenges of nano drug delivery are reviewed. Nanotechnology is one approach to overcome challenges of conventional drug
delivery systems based on the development and fabrication of nanostructures. Some challenges associated with the technology as it relates to drug effectiveness, toxicity, stability, pharmacokinetics and drug regulatory control are discussed in this review. Clearly, nanotechnology is a welcome
development that is set to transform drug delivery and drug supply chain management, if optimally developed.
