Inter-polyionic orientation in polyelectrolyte solution, observed by small angle neutron scattering

2014 An intensity peak in small angle neutron scattering in a polyelectrolyte solution is found above a characteristic concentration c0 of the polyelectrolyte. This is taken as evidence for ordering between the elongated polyions.

Heparin's solution structure determined by small-angle neutron scattering.

Heparin is a linear, anionic polysaccharide that is widely used as a clinical anticoagulant. Despite its discovery 100 years ago in 1916, the solution structure of heparin remains unknown. The solution shape of heparin has not previously been examined in water under a range of concentrations, and here is done so in D2 O solution using small-angle neutron scattering (SANS). Solutions of 10 kDa h...

Small angle neutron scattering

Small Angle Neutron Scattering (SANS) is a technique that enables to probe the 3-D structure of materials on a typical size range lying from ∼ 1 nm up to ∼ a few 100 nm, the obtained information being statistically averaged on a sample whose volume is ∼ 1 cm3. This very rich technique enables to make a full structural characterization of a given object of nanometric dimensions (radius of gyrati...
