Time-resolved SANS will be used to investigate the mechanisms and kinetics of ordering of aseries of novel designed tetrapeptide-based hydrogelators. These inexpensive materials arebiocompatible and biofunctional and may find applications in medicine. Peptide hydrogels have been the subject of many studies using TEM and SEM but there are very few neutron scattering studies focussed on the mechanisms of aggregation. TEM shows that several of the tetrapeptide hydrogelators self-assemble into fibrils. The kinetics and mechanisms of this process, and its dependence on preparationconditions, will be examined by SANS.
