The aim of the present investigation is to explain the application of ferrofluid (Fe3O4) as target drug delivery system in nanotechnology. It works on the principle of Magnetism which plays an important role in different application of ferrofluid in medicine. Ferrofluid is biocompatible and therefore it is one of the most extensively used biomaterials for different application ranging from cell...

magnetic resonance imaging (mri) contrast agents most commonly agents used in diagnosing different diseases. several agents have been ever introduced with different peculiar characteristics. they vary in potency, adverse reaction and other specification, so it is important to select the proper agent in different situations. we conducted a systematic literature search in medline/pubmed, web of s...

The primary limitation of magnetic drug targeting (MDT) relates to the strength of an external magnetic field which decreases with increasing distance. Small nanoparticles (NPs) displaying superparamagnetic behaviour are also required in order to reduce embolization in the blood vessel. The small NPs, however, make it difficult to vector NPs and keep them in the desired location. The aims of th...

The implant assisted magnetic targeted drug delivery system of Avilés, Ebner and Ritter is considered both experimentally (in vitro) and theoretically. The results of a 2D mathematical model are compared with 3D experimental results for a magnetizable wire stent. In this experiment a ferromagnetic, coiled wire stent is implanted to aid collection of particles which consist of single domain magn...

In the 1960s, discovery of pleasure system (defined as reward system) in the brain that may underlie drug reward and addiction encouraged many scientists to investigate the mechanisms by which drug abuse affects central nervous system function. In this regard, investigators developed several drugs targeting the brain reward system for drug dependence therapy. However, no positive results obtain...
