      abstract     = {Ionophores are an important class of synthetic molecules
                      which mimic natural ion channels or carriers. Here we report
                      the aggregation behavior in pseudo-physiological environment
                      of three Cyclic Phosphate-Linked Oligosaccharides (CyPLOS)
                      derivatives, synthetic ion transporters based on cyclic,
                      phosphate-linked disaccharide skeleton differing for the
                      nature of the tails (tetraethylene-TEG glycol and/or
                      n-undecyl chains) attached to the C-2 and C-3 of the
                      constitutive monosaccharides. Their aggregation behavior has
                      been studied by a combined use of dynamic light scattering
                      (DLS), electron paramagnetic resonance spectroscopy (EPR)
                      and Small Angle Neutron Scattering (SANS). DLS measurements
                      were performed to reveal the formation and size distribution
                      of the CyPLOS aggregates. EPR measurements, by using 5-doxyl
                      stearic acid (5-DSA) as spin-probe, showed that the
                      aggregates are mainly due to the formation of double layers
                      and allowed to analyze the local fluidity. Finally, SANS
                      measurements allowed estimating the layer thickness of the
                      double layers. Our results indicate that the three CyPLOS
                      analogs show self-aggregation properties that depend on the
                      different nature of the inserted tails.},
