Small-angle neutron scattering dendrimers

Chen W-R, Porcar L, Liu Y, Butler PD, Magid LI. Small angle neutron scattering studies of the counterion effects on the molecular conformation and strucmre of charged G4 PAMAM dendrimers in aqueous solutions. Macromolecules 2007 40 5887-5898. 

Most studies performed partly on molecular models [33] but also on real POPAM and PAMAM dendrimers support the latter model concept [34]. Careful studies on the three-dimensional structure of flexible dendrimers in solution were performed by Ballauff et al. by means of SANS (Small Angle Neutron Scattering) [35] (see Section 7.6).

The stmaural characterization of dendrimers has been a challenge for many years. Small-angle neutron scattering (SANS) experiments, where a neutron beam is elastically scattered due... 

Variation of contrast [46] is an important experimental technique in neutron small-angle scattering. Above and beyond size determination, it affords detailed insights into the internal structure of dissolved dendrimers and even permits the location of selected components of the molecule which have been previously labelled with deuterium.
