    • Protection of astaxanthin from photodegradation by its inclusion in hierarchically assembled nano and microstructures with potential as food 

      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 ...
