Control of molecular gelation by chemical stimuli
Segarra Maset, María Dolores; Nebot Carda, Vicent J.; Miravet, Juan; Escuder, Beatriu Royal Society of Chemistry (2012-12-21)Molecular gels are formed by the self-assembly of low-molecular weight compounds by weak non-covalent interactions and thus, they may be easily disassembled in response to external stimuli. Chemically sensitive gels can ... -
Freezing Capture of Polymorphic Aggregates of Bolaamphiphilic L-Valine-Based Molecular Hydrogelators
Nebot Carda, Vicent J.; Diaz-Oltra, Santiago; Smets, Johan; Fernández Prieto, Susana; Miravet, Juan; Escuder, Beatriu WILEY-VCH Verlag GmbH & Co. KGaA (2014-05)Nanostructured xerogels have been prepared by the freeze-drying of hydrogels and aggregates formed by bolaamphiphilic l-valine derivatives after aging under different environmental conditions. A wide variety of shapes and ... -
Interplay of Molecular Hydrogelators and SDS Affords Responsive Soft Matter Systems with Tunable Properties
Nebot Carda, Vicent J.; Escuder, Beatriu; Miravet, Juan; Smets, Johan; Fernández Prieto, Susana American Chemical Society (2013)The gelation efficiency of low molecular weight bolaamphiphilic hydrogelators 1 and 2 is influenced by the presence of SDS micelles. Similarly, the critical micellar concentration value of SDS is reduced in the presence ... -
Molecular Hydrogels from Bolaform Amino Acid Derivatives: A Structure–Properties Study Based on the Thermodynamics of Gel Solubilization
Nebot Carda, Vicent J.; Armengol Fernández, José; Smets, Johan; Fernández Prieto, Susana; Escuder, Beatriu; Miravet, Juan Wiley (2012-03)Insight is provided into the aggregation thermodynamics associated to hydrogel formation by molecular gelators derived from L-valine and L-isoleucine. Solubility data from NMR measurements are used to extract thermodynamic ... -
Rational Design of Heat-Set and Specific-Ion-Responsive Supramolecular Hydrogels Based on the Hofmeister Effect
Nebot Carda, Vicent J.; Ojeda, Juan José; Smets, Johan; Fernández Prieto, Susana; Escuder, Beatriu; Miravet, Juan WILEY-VCH Verlag GmbH & Co. KGaA (2014-10)Smart supramolecular hydrogels have been prepared from a bolaamphiphilic l-valine derivative in aqueous solutions of different salts. The hydrogels respond selectively to different ions and are either reinforced or weakened. ... -
Two-Component Peptidic Molecular Gels for Topical Drug Delivery of Naproxen
Martí-Centelles, Rosa; Dolz Pérez, Irene; De la O, Jaciel; Ontoria Oviedo, Imelda; Sepulveda, Pilar; Nebot Carda, Vicent J.; Vicent, Maria J.; Escuder, Beatriu American Chemical Society (2021-01-05)Transdermal drug delivery (TDD) is an advantageous and effective approach for the localized delivery of drugs; however, overcoming the high impermeability of the outermost layer of skin, the stratum corneum, represents a ... -
Vibrational Circular Dichroism Shows Reversible Helical Handedness Switching in Peptidomimetic l-Valine Fibrils
Nieto Ortega, Belén; Nebot Carda, Vicent J.; Miravet, Juan; Escuder, Beatriu; López Navarrete, Juan T.; Casado, Juan; Ramírez, Francisco J. American Chemical Society (2012)We elucidate the supramolecular organization in the form of microsize fibrils of gels formed by a l-Valine peptidomimetic compound. Analysis was based on circular dichroism spectroscopies, vibrational (VCD) and electronic ...
