Recent advances in nanoparticle-mediated drug delivery

The engrossment towards controlled drug delivery seeks the development of suitable drug carriers that can transmit a sufficient dose of the drug to diseased lesions. Various nanostructures including liposomes, polymers, dendrimers, and magnetic nanoparticles have been tested as carriers in drug delivery. Nanoparticles make it possible to achieve improved delivery of drugs which are poorly soluble in water by delivering drug of small particle size allowing faster dissolution in blood stream leading to targeted drug delivery in a cell- or tissue-specific manner. This article provides an overview of the recent developments in the preparation and use of nanoparticles in drug delivery.
