**6. Conclusions and perspectives**

The general lines of polymer functionalization with cyclodextrins and resulting changes of their properties have been reviewed in this chapter. These can be applied for generating and studying other polymer-cyclodextrin systems. The EPR spectroscopy can be used as a method for proving changes at nanoscale level in such systems due to host-guest interactions occurring in polymer systems. The EPR data can be linked with other experimental data provided by classical methods used to characterize polymers in solution and in gel states, like rheology, electron microscopy techniques, etc.
