However, when the relative viscosity was plotted as a function of molar fraction of the dendritic polymer, the solution viscosities were seen to be clearly concentration dependent.
In this research, a drug delivery system was developed by using carbon nanotubes, linear dendritic polymer, iron nanoparticles, and doxorubicin anti-cancer drug.

In September 2013, Iranian researchers from Lorestan University succeeded in designing a new type of drug delivery system for anti-cancer drugs by using linear dendritic polymers and iron nanoparticles.
Their topics include dendrimer-nanoparticle conjugates in nano-medicine, dendritic polymers for the repair of tissues, the theranostic potential of dendronized iron oxide nanoparticles, structurally flexible and amphiphilic poly(amidoamine) dendrimers as non-viral vectors for siRNA delivery, and the impact of physico-chemical properties on dendrimer pharmacokinetics and biodistribution.
The dendritic polymers mimic the hydrodynamic volume of spheres in solution and shows low viscosity in the melt, even at high molecular weight, due to the lack of restrictive interchain entanglements.
