Dendrimers are the polymers of 20th century having different and better functional properties than conventional linear polymers. Dendrimers are synthetic three dimensional strictly architectured polymers having some exclusive features like multiple surface functionality, highly branched structure, uniform size and molecular weight and having internal cavities for enclosing drug molecules. These distinguishing properties render them effective nano carrier for drug delivery in cancer tissues and for other targeted deliveries. In respective applications, dendrimers still need to be explored for their bio safety and toxicity study. Dendrimers are commercialized for diagnostic and gene transfecting agents. This review mainly focuses on basic structure, properties, types and potential applications of dendrimers in drug delivery.
