Amphiphilic ionic complexes of hyaluronic acid with organophosphonium compounds and their antimicrobial activity
Gamarra Montes, Ana; Forés Gil, Eva; Morató Farreras, Jordi; Muñoz Guerra, Sebastián (2018-01-01)
Article
Accés obertAmphiphilic ionic complexes of hyaluronic acid and alkyltrimethylphosphonium soaps with alkyl chains containing even numbers of carbons from 12 to 22 have been produced. The complexes have a nearly stoichiometric composition, ... -
Antibacterial films made of ionic complexes of poly(y-glutamic acid) and ethyl lauroyl arginate
Gamarra Montes, Ana; Missagia, Beatriz; Morató Farreras, Jordi; Muñoz Guerra, Sebastián (2017-12-24)
Article
Accés obert© 2017 by the author. The biocide agent LAE (ethyl aN-lauroyl l-arginate chloride) was coupled with poly(y-glutamic acid) (PGGA) to form stable ionic complexes with LAE:PGGA ratios of 1 and 0.5. The nanostructure adopted ... -
Comblike ionic complexes of hyaluronic acid and alkanoylcholine surfactants as a platform for drug delivery systems
Gamarra Montes, Ana; Muñoz Guerra, Sebastián; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Thérien-Aubin, Héloïse; Landfester, Katharina (2018-09-10)
Article
Accés obertNontoxic alkanoylcholine soaps (nACh) were synthesized from choline and fatty acids with numbers of carbons n equal to 12, 14, 16, and 18, the latter including both saturated and 9-cis unsaturated alkanoyl chains. Coupling ... -
Crystalline structure and thermotropic behavior of alkyltrimethylphosphonium amphiphiles
Gamarra Montes, Ana; Urpí Garriga, Lourdes; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Muñoz Guerra, Sebastián (2017-02-14)
Article
Accés obertQuaternary organophosphonium salts bearing long alkyl chains are cationic surfactants of interest owing to their physical and biological properties. In the present work, the crystal structure and thermotropic behavior of ... -
Ionic complexes of naturally-occurring biopolymers and cationic surfactants : a platform for industrial and biomedical applications
Gamarra Montes, Ana (Universitat Politècnica de Catalunya, 2018-07-13)
Tesi
Accés obertIn recent years, the increasing public concern about the environmental pollution caused by persistent plastic wastes has stimulated the interest in replacing synthetic polymers by biopolymers. The term biopolymer refers ... -
Ionic complexes of poly(gamma-glutamic acid) with alkyltrimethylphosphonium surfactants
Gamarra Montes, Ana; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Vives, Marc; Morató Farreras, Jordi; Muñoz Guerra, Sebastián (Elsevier, 2017-05-05)
Article
Accés obertA series of ionic complexes with a comb-like architecture and a nearly stoichiometric composition were prepared from bacterial poly(gamma,dl-glutamic acid) (PGGA) and alkyltrimethyl phosphonium bromides (nATMP·Br) bearing ... -
Ionic coupling of hyaluronic acid with ethyl N-lauroyl L-arginate (LAE): Structure, properties and biocide activity of complexes
Gamarra Montes, Ana; Missagia, Beatriz; Urpí Garriga, Lourdes; Morató Farreras, Jordi; Muñoz Guerra, Sebastián (2018-10-01)
Article
Accés obertEthyl alpha-N-lauroyl L-arginate hydrochloride (LAE) was coupled with hyaluronic acid (HyA) 2 to form ionic complexes with LAE to HyA ratios of 1:1 and 1:2. The complexes were extensively 3 characterized by FTIR and NMR ... -
Nanocomposites of microbial polyglutamic acid and nanoclays compatibilized by organophosphonium surfactants
Gamarra Montes, Ana; Muñoz Guerra, Sebastián; Urpí Garriga, Lourdes; Galbis Fuster, Elsa; Galbis Pérez, Juan Antonio (2018-01-01)
Article
Accés obertIonic coupling of bacterial poly(¿-glutamic acid) (PGGA) with alkyltrimethylphosphonium surfactants is reported to render comb-like PGGA complexes with a biphasic-layered structure displaying periodicity at the nanoscopic ... -
Nanostructured amphiphilic systems based on hyaluronic acid ionic complexes
Gamarra Montes, Ana; Alla Bedahnane, Abdelilah; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Casas Becerra, María Teresa; Muñoz Guerra, Sebastián (2016)
Text en actes de congrés
Accés obertIn this communication we wish to report on HyA ionic complexes prepared by coupling with a) choline-based surfactants (nACh·HyA complexes), and b) alkylphosphonium surfactants (nATMP·HyA complexes) with n being the number ...
