Nanoparticles & Nanotechnology : Clinical, Toxicological, Social, Regulatory & other aspects of Nanotechnology

In last few decades, there has been a considerable research interest in the area of drug delivery using particulate delivery systems as carriers for small and large molecules like nanoparticles. The continuing advancement of nanotechnology represents a tremendous opportunities of society because of the unique traits that nanoscale material possess but there are many clinical, toxicological, social, regulatory and other aspects of nanotechnology which are matter of concern. The United States Food and Drug Administration (FDA) and some other authorities ensures that the nanoparticle based products meet the regulatory standards for approval but like other new technologies there are many ethical issues and regulatory challenges associated with the products of nanotechnology. Before nanotechnology is largely used to enhance the quality of life, it must be made certain that health risks are taken in to the consideration, social and ethical issues are addressed, public opinions are gathered, and regulatory matters are assessed from all aspects.
