Dynamic Peptide Library for the Discovery of Charge Transfer Hydrogels
Berdugo Gumbau, Cristina; Nalluri, Siva Krishna Mohan; Javid, Nadeem; Escuder, Beatriu; Miravet, Juan; Ulijn, R. V. ACS Publications (2015)Coupling of peptide self-assembly to dynamic sequence exchange provides a useful approach for the discovery of self-assembling materials. In here, we demonstrate the discovery and optimization of aqueous, gel-phase ... -
Structural insight into the aggregation of L-prolyl dipeptides and its effect on organocatalytic performance
Berdugo Gumbau, Cristina; Escuder, Beatriu; Miravet, Juan Royal Society of Chemistry (2015)NMR and organocatalytic studies of four dipeptides derived from L-proline are described. Results indicate that important conformational changes around the catalytic L-proline moiety are observed for free dipeptides upon ... -
Study of the effect of polymorphism on the self-assembly and catalytic performance of an L-proline based molecular hydrogelator
Diaz-Oltra, Santiago; Berdugo Gumbau, Cristina; Miravet, Juan; Escuder, Beatriu Royal Society of Chemistry (2015)An exhaustive study of the polymorphism found for aggregates and hydrogels of an L-proline based hydrogelator under different preparation conditions is undertaken. The effect of heating temperature, aging time, ultrasound ... -
Substrate selective catalytic molecular hydrogels: the role of the hydrophobic effect
Berdugo Gumbau, Cristina; Miravet, Juan; Escuder, Beatriu Royal Society of Chemistry (2013-09-17)A catalytic hydrogel is reported for the substrate selective direct aldol reaction of aliphatic ketones based on their hydrophobicity and on the emergence of catalytic activity only after self-assembly of the catalyst. -
Tuning Chelation by the Surfactant-Like Peptide A(6)H Using Predetermined pH
Castelletto, Valeria; Hamley, Ian W.; Segarra Maset, María Dolores; Berdugo Gumbau, Cristina; Miravet, Juan; Escuder, Beatriu; Seitsonen, J.; Ruokolainen, J. American Chemical Society (2014)We examine the self-assembly of a peptide A6H comprising a hexa-alanine sequence A6 with a histidine (H) “head group”, which chelates Zn2+ cations. We study the self-assembly of A6H and binding of Zn2+ ions in ZnCl2 ...
