Dendrimers are a new class of polymeric materials. They are highly branched, monodisperse macromolecules. The structure of these materials has a great impact on their physical and chemical properties. As a result of their unique behaviour dendrimers are suitable for a wide range of targeted drug delivery, controlled drug delivery, gene delivery and industrial applications. The paper gives a concise review of dendrimers physico-chemical properties, types, synthetic pathway & their possible use in various aspects of research, technology and treatment of disease. Key words: Dendrimer, targeted drug delivery, gene delivery, dendrimer synthesis, dendrimer properties, dendrimer types.
