Use of Nanoparticles in DDS and Newer Methodologies

A particle with at least one dimension less than 100nm is a nanoparticle. They are composed of synthetic or semisynthetic polymers carrying drugs or proteinaceous substances. Nanoparticles have developed as capable vehicles to deliver drugs in the body. Nanoparticles comprising encapsulated, dispersed, absorbed or conjugated drugs have exceptional characteristics that can lead to higher performance in a variety of dosage forms. Nanoparticles are one of the novel drug delivery systems which can be of potential use in controlling and targeting drug delivery as well as in cosmetic textiles and paints. There are recent developments in the use of nanoparticles as drug delivery systems to treat a wide variety of diseases.
