The Interplay of Aggregation, Fibrillization and Gelation of an Unexpected Low Molecular Weight Gelator: Glycylalanylglycine in Ethanol/Water

Hydrogels formed by polypeptides could be much-favored tools for drug delivery because their main ingredients are generally biodegradable. However, the gelation of peptides in aqueous solution generally requires a minimal length of the peptide as well as distinct sequences of hydrophilic and hydrophobic residues.

The impact of thermal history on the structure of glycylalanylglycine ethanol/water gels

This work revisits several open questions regarding the mechanisms of GAG fibril formation and structure as a function of temperature.
