Nanotechnology has great benefits in the area of pharmaceutical researches and applications. It is used to create small features on software’s and computers chips for last 25 years. The major principal that makes the nanomaterial differ from other material are the enhanced surface area and quantum effects; so that the properties like strength, reactivity, electrical behaviour etc. are enhanced. While the quantum effects affect the magnetic, optical and electrical behaviour of materials. In the pharmaceutical area nanotechnology has been widely used for the targeting drug delivery. Recently the developments in nanotechnology have shown that nanomaterials have a great potential as drug carriers. Their small sizes make them physiologically and biologically, a favourable material for biomedical applications. The present study reviews some of the recent biomedical applications of nanotechnology.
