Dendrimers chemistry is one of the most rapidly expanding area of modern chemistry. Dendrimers are nano-sized radially symmetric molecule with well-defined homogeneous and monodisperse structure that has a typically symmetric core an inner shell an outer shell. Dendrimers are a promising drug tool, widely, been explored for the treatment, diagnosis or theragnostic purpose. A variety of dendrimers exist, and each has biological properties such as polyvalency, self- assembling, electrostatic, interactions, chemical stability, low toxicity and solubility. Dendrimers has highly compact and tree-like branched structure as well as the uniform size in the nanometer size range have attracted tremendous scientific interest in many fields such as nano- material, biochemistry, supermolecule, drug delivery system etc.
