Part of the Biotechnology: Pharmaceutical Aspects book series (PHARMASP, volume X)


Nanosized controlled release systems for drug delivery are segregated into several categories including polymeric nanoparticles, liposomes, solid lipid nanoparticles, polymeric micelles, and dendrimers. This topic is extensive and as such is only briefly reviewed here. More detailed information may be found in more focused chapters of this book. With this in mind, this chapter will provide an overview of nanoparticulate systems, followed by some of the more interesting opportunities and applications of nanotechnology in controlled release: metal–organic systems, nanotubes, responsive systems, and personal care products.

The use of a drug as a therapeutic agent is often a delicate balance between therapeutic efficacy and detrimental side effects including toxicity. The control of the amount of drug delivered over time and the spatial localization of that delivery are paramount in overcoming the challenges of providing optimal therapy. This challenge drives the design of...
