    • Photochromic Solid Materials Based on Poly(decylviologen) Complexed with Alginate and Poly(sodium ... 
      Sanhueza, Luis; Castro, Joaquín; Urzúa, Esteban; Barrientos, Lorena; Oyarzún Ampuero, Felipe; Pesenti, Héctor; Shibue, Toshimichi; Sugimura, Natsuhiko; Tomita, Wataru; Nishide, Hiroyuki; Moreno Villoslada, Ignacio (American Chemical Society, 2015)
      Photochromic solid materials based on the cationic polymer poly(decylviologen) are reported. The solids were obtained by freeze-drying colloidal suspensions of nanocomplexes obtained by mixing aqueous solutions of the ...
    • Polymeric nanoparticles for increasing oral bioavailability of curcumin 
      Umerska, Anita; Gaucher, Caroline; Oyarzún Ampuero, Felipe; Fries Raeth, Isabelle; Colin, Florence; Villamizar Sarmiento, María Gabriela; Maincent, Philippe; Sapin Minet, Anne (MDPI, 2018-04)
      Despite the promising biological and antioxidant properties of curcumin, its medical applications are limited due to poor solubility in water and low bioavailability. Polymeric nanoparticles (NPs) adapted to oral delivery ...
    • 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 ...
    • Synthesis of tuneable amphiphilic-modified polyketone polymers, their complexes with 5,10,15,20-tetrakis- ... 
      Araya Hermosilla, Esteban; Roscam Abbing, Marnix; Catalán-Toledo, José; Oyarzún Ampuero, Felipe; Pucci, Andrea; Raffa, Patricio; Picchioni, Francesco; Moreno-Villoslada, Ignacio (Elsevier Ltd, 2019)
      A series of amphiphilic polymers bearing aliphatic secondary amines and hydroxyl groups have been synthesized showing different hydrophilic/hydrophobic balance. The synthesis is performed through the Paal-Knorr modification ...
    • 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 ...
