      Aerogels made of chitosan and chondroitin sulfate, and containing 5,10,15,20-tetrakis-(4- sulfonatophenyl)-porphyrin have been synthesized. The aerogels presented a microstructure made of microfibers and microsheets, ...
    • Association Efficiency of Three Ionic Forms of Oxytetracycline to Cationic and Anionic Oil-In-Water ... 
      Orellana, Sandra L.; Torres Gallegos, César; Araya Hermosilla, Rodrigo; Oyarzún Ampuero, Felipe; Moreno Villoslada, Ignacio (John Wiley, 2015)
      The association efficiency of oxytetracycline (OTC) to pharmaceutical available, ionic oil-in-water nanoemulsions is studied. Theoretical mathematical developments allowed us to differentiate by diafiltration (DF) between ...
    • Confinement of 5,10,15,20-tetrakis-(4-sulfonatophenyl)-porphyrin in novel poly (vinylpyrrolidone) s modified ... 
      Gómez Tardajos, Myriam; Pino Pinto, Juan Pablo; Díaz Soto, Claudia; Flores, Mario E.; Gallardo, Alberto; Elvira, Carlos; Reinecke, Helmut; Nishide, Hiroyuki; Moreno Villoslada, Ignacio (Elsevier, 2013)
      Polymeric derivatives of the biocompatible poly(vinylpyrrolidone) bearing discrete amounts of aromatic amines have been synthesized. The interaction of 5,10,15,20-tetrakis-(4-sulfonatophenyl)-porphyrin with a series of ...
    • Diseño, desarrollo y caracterización de nanopartículas basadas en interacciones Π-Π fármaco-polímero para ... 
      Villamizar Sarmiento, María Gabriela (Universidad de Chile, 2020)
      La administración de fármacos hidrofílicos de bajo peso molecular constituye un gran desafío en drug delivery, sobre todo para la terapia de enfermedades crónicas. La biodistribución parcial y rápida eliminación de estas ...
    • Formación de agregados supramoleculares de anfifilos no iónicos en medio no acuoso. Efecto ligante del agua 
      Flores Flores, Mario Enrique (Universidad de Chile, 2015)
      El trabajo a continuación explora el proceso de asociación de moléculas anfifílicas no iónicas en solventes apolares y el efecto ligante del agua en este proceso de asociación. En específico, se han estudiado tres moléculas ...
