The association of M-polynomial to chemical compounds and chemical networks is a
relatively new idea, and it gives good results about the topological indices. These results are
then used to correlate the chemical compounds and chemical networks with their chemical
properties and bioactivities. In this paper, an effort is made to compute the general form of
the M-polynomials for two classes of dendrimer nanostars and four types of nanotubes.
These nanotubes have very nice symmetries in their structural representations, which have …
