Topological properties of benzenoid, phenylenes and nanostar dendrimers.

A variety of dendrimers exist, and each has biological properties such as polyvalency, selfassembling, electrostatic interactions, chemical stability, low cytotoxicity, and solubility. These varied characteristics make dendrimers a good choice in the medical field and pharmaceuticals. A topological index is actually designed by transforming a molecular structure into a numeric number. These topological indices correlate certain physicochemical properties like boiling point, stability, strain energy etc of chemical compounds. It is reported that these indices are useful in the study of anti-in ammatory activities, anticancer therapies and diagnostic imaging of certain chemical networks. In this paper, we determine hyper Zagreb index, first multiple Zagreb index, Second multiple Zagreb index, Zagreb polynomials for nanostar dendrimers, Benzenoid and phenylenes. [ABSTRACT FROM AUTHOR]
