Application of Nanotechnology in Drug Delivery

Abstract

Nanotechnology has potential to bridge the gaps of biological and physical sciences by applying nanostructures and nanophases at various applications of biomedical science, more explicitly in nanomedicine. Nanomedicine is of major concern for biomedical application owing to fascinating applications in the field of drug delivery and disease diagnosis. Nanomedicine and nano-delivery systems are moderately latest fields but quickly emerging science where substances in the nanorange are exploited to offer a means for diagnostic tools or to carry therapeutically active substances to specific targeted sites in a controlled manner. In this chapter, the benefits of nanotechnology in drug-delivery applications are examined. The transport of therapeutic agents to their desired sites occurs by employing different nanosystems. Over the several years, drug-delivery systems more precisely the nanosystems have emerged into diverse forms of second-generation drug-delivery systems, including nanobots, injectable nanoparticle generator, nanoghosts, niosomes, nanoclews, carbon nanotubes, nanocrystals. A detailed description of these systems has been also included. As nanotechnology offers multiple benefits in treating various human diseases, we have provided an updated review of current advances in the field of nanomedicines and nano-based drug-delivery systems through inclusive inspection of the discovery and application of nanomaterials in improving the efficacy of both new and old drugs.
