      abstract     = {The response to pH variation of polymeric
                      cyclodextrin-based hydrogels has been investigated by a
                      multi-technique approach based on UV Raman and Brillouin
                      light scattering (BLS) together with Small Angle Neutron
                      Scattering (SANS). By exploiting the complementary
                      information of these three investigation methods, the
                      structural, viscoelastic and molecular modifications of the
                      polymer brought about by the pH changes have been examined,
                      over a spatial range going from mesoscopic to nanoscopic
                      length-scale. The data provide a picture where an increase
                      of pH promotes the change of the characteristic size of the
                      hydrophilic pores when the cross-linker has the suitable
                      structural and acid-base properties, and leads to the
                      reinforcement of the polymer domains interconnections,
                      providing a stiffer gel network on the length-scale probed
                      by BLS. Raman signals are sensitive both to structural
                      changes of the polymer network and to changes of the
                      intermolecular ordering of water due to solvent-polymer
                      interactions. The destructuring effect on the tetrahedral
                      ice-like configurations of water is especially evident at
                      high pH, and might be ascribed to an increased exposition to
                      the solvent of the ionic portions of the polymer surface.},
