    • Antibacterial activity against Staphylococcus aureus of chitosan/chondroitin sulfate nanocomplex aerogels ... 
      Angélica Gómez, María; Marcela Bonilla, Jennifer; Alejandra Coronel, María; Martínez, Jonathan; Moran Trujillo, Luis; Orellana, Sandra L.; Vidal, Alejandra; Giacaman, Annesi; Morales, Carlos; Torres Gallegos, Cesar; Concha, Miguel; Oyarzún Ampuero, Felipe; Godoy, Patricio; Lisoni, Judit G.; Henríquez Baez, Carla; Bustos, Carlos; Moreno Villoslada, Ignacio (Walter de Gruyter GMBH, 2018-04)
      The antibacterial activity against Staphylococcus aureus of aerogels fabricated from colloidal suspensions of chitosan/chondroitin sulfate nanocomplexes is analyzed. Upon freeze-drying the colloidal suspensions, the aerogels ...
    • Application of chitosan and chondroitin sulphate aerogels in a patient with diabetes with an open forefoot ... 
      Vidal, Alejandra; Giacamán, Annesi; Orellana, Sandra S.; Jofré, Sandra; Moreno Villoslada, Ignacio; Oyarzún Ampuero, Felipe; Concha, Miguel (H M P Communications, 2020)
      Introduction. Diabetic foot ulcers may lead to nontraumatic amputations of the foot, leading to a decrease in patient quality of life. Transmetatarsal amputations (TMAs) represent an effective surgical procedure in cases ...
    • Chitosan/chondroitin sulfate aerogels with high polymeric electroneutralization degree: formation and ... 
      Orellana, Sandra L.; Giacaman, Annesi; Vidal, Alejandra; Morales, Carlos; Oyarzún Ampuero, Felipe; Lisoni, Judit G.; Henríquez Baez, Carla; Moran Trujillo, Luis; Concha Nordemann, Miguel; Moreno Villoslada, Ignacio (Walter de Gruyter GMBH, 2018-04)
      The formation of ultralight, highly porous solid materials (porosity higher than 99 %) containing equivalent molar amounts of chitosan (CS) and chondroitin sulfate (ChS) is presented. First, we show protocols to produce ...
    • Facile Formation of Redox-Active Totally Organic Nanoparticles in Water by In Situ Reduction of Organic ... 
      Flores, Mario E.; Garcés Jerez, Pablo; Fernández, Daniel; Aros Pérez, Gustavo; González Cabrera, Diego; Álvarez, Eduardo; Cañas, Ignacio; Oyarzún Ampuero, Felipe; Moreno Villoslada, Ignacio (Wiley, 2016)
      The formation of redox-active, totally organic nanoparticles in water is achieved following a strategy similar to that used to form metal nanoparticles. It is based on two fundamental concepts: i) complexation through ...
    • Mechanical properties and electrical surface charges of microfibrillated cellulose/imidazole-modified ... 
      González Cortes, Pablo; Araya Hermosilla, Rodrigo; Araya Hermosilla, Esteban; Acuña, Daniela; Mautner, Andreas; Caballero, Leonardo; Melo, Francisco; Moreno Villoslada, Ignacio; Picchioni, Francesco; Rolleri, Aldo; Quero, Franck (Elsevier, 2020)
      In the present work, microfibrillated cellulose (MFC) suspensions were produced by high-pressure homogenization and subsequently used to fabricate MFC membranes (C-1) by vacuum filtration followed by hot-pressing. A ...
    • Protection of astaxanthin from photodegradation by its inclusion in hierarchically assembled nano and ... 
      Alarcón-Alarcón, Carlos; Inostroza-Riquelme, Mariela; Torres Gallegos, César; Araya, Claudio; Miranda, Miguel; Sánchez-Caamaño, Juan; Moreno Villoslada, Ignacio; Oyarzún Ampuero, Felipe (Elsevier, 2018-10)
      Astaxanthin is a light sensitive molecule which is already approved as a dietary supplement, with a wide range of biological properties in humans and fishes. In this paper, we provide strategies to photostabilize the pigment ...
    • Totally organic redox active pH sensitive nanoparticles stabilized by amphiphilic aromatic polyketones 
      Araya Hermosilla, Esteban; Catalán Toledo, Jose; Muñoz Suescun, Fabián; Oyarzún Ampuero, Felipe; Raffa, Patrizio; Massimo Polgar, Lorenzo; Picchioni, Francesco; Moreno Villoslada, Ignacio (American Chemical Society, 2018)
      Amphiphilic aromatic polymers have been synthesized by grafting aliphatic polyketones with 4-(aminomethyl)benzoic acid at different molar ratios via the PaalKnorr reaction. The resulting polymers, showing diketone conversion ...
