Fast and slow dynamics of water-soluble dendrimers consisting of amido-amine repeating units by neutron spin-echo
Article Abstract:
Neutron Spin-Echo (NSE) experiments are performed at room temperature on D2O solutions of fifth generation poly(amido amine) dendrimers with different types of end groups. It is observed that the diffusion coefficient of the slow mode corresponds to translational diffusion coefficient and the fast mode originates from the motion of amido-amine segments in the dendrimers, which is a common internal unit for the two dendrimers.

Small-angle neutron scattering investigations of layer-block dendrimers in aqueous solutions
Article Abstract:
The structures of ploy/mono dendrimer with hydroxyl end groups and poly-dendrimer with galactose having glycopeptide end groups were characterized in aqueous solutions and compared with that of poly-dendrimer with hydroxyl end groups. The external contrast variation results of small-angle neutron scattering suggested the segment density distribution in dendrimers.

Structure-selective dye uptake into an aggregate of a copolymer with linear polyelectrolyte block hydrophobic block carrying pendant dendritic moiety in water
Article Abstract:
Selective uptake of various dyes into an aggregate of amphiphilic copolymer consisting of hydrophilic linear polyelectrolyte block and hydrophobic block carrying pendant dendritic moiety is investigated in water. The copolymer associated into an aggregate with a hydrophobic interior at concentrations above 0.2 mg cm(super -3) is reported.
