Time resolved investigation of themicrostructure of dipeptide hydrogels
Low molecular weight gelators (LMWG) are molecules that self-assemble into one dimensional fibres that entangle and for a network. Under the right conditions, a self-supporting gel is formed. We have found that the process by which the self-assembly is conducted has a dramatic effect on the fins gel properties. To understand this, it is critical to understand the early time assembly processes that lead to the final network type. For dipeptide LMWG, a common method is to dissolve in a solvent and then add water. This leads to a nucleation and growth process (see for example Soft Matter, 2011, 7 9721). It is clear that the nucleation process determines the final properties, but the structures formed at early times are highly transient and difficult to characterise. Here, we propose to use the stop flow cell to probe the structures formed at early times.
