A review on unique Targeted drug carrier system

Dendrimers are repeatedly branched, roughly spherical large molecules. The name comes from the Greek word dendron, which translates to "tree". Synonymous terms for dendrimer include arborols and cascade molecules. However, dendrimer is currently the internationally accepted term. A dendrimer is typically symmetric around the core, and often adopts a spherical three-dimensional morphology. The word dendron is also encountered frequently. A dendron usually contains a single chemically addressable group called the focal point. Dendrimers are a new class of three-dimensional, man-made molecules produced by a usual synthetic route which incorporates repetitive branching sequences to create a unique novel architecture. These are highly controlled structures with all bonds emanate from a core and like a tree.
