Patents Assigned to Fundación Fraunhofer Chile Research
  • PAMAM, spacer molecule and cafestol polymers
    Patent number: 9198973
    Abstract: The present invention is directed to a polymeric compound with a size in a nanometric scale, useful as a biocompatible carrier for the transport and delivery of active agents into a fish, insect, animal, reptile, bird, human, or plant, wherein said polymeric compound comprises PAMAM (polyamidoamine) dendrimers, a spacer molecule, and cafestol, wherein the polymeric compound of the invention comprises a structure of the kind (cafestol-PAMAM derivative)2-spacer molecule. Use of the compound as a biocompatible carrier for transport and delivery of antithrombotic active agents is disclosed. Procedures for obtaining a polymeric compound comprising the activation of cafestol, activation of polyethylene glycol, and formation of cafestol-PAMAM-PEG-PAMAM-cafestol are also disclosed.

  • Toxic phenolic compound removal by selective binding of phenolic compounds using smart polymers
    Patent number: 8927042
    Abstract: The present invention corresponds to a method for the removal of unwanted toxic phenolic compounds such as a pesticide from foodstuffs, more particularly beverages. The method comprising contacting a selected polymer with the foodstuff. In a particular embodiment, the polymers are selected among polyaniline (PANI), polyaniline emeraldine base (PANI-EB) and polyaniline emeraldine salt (PANI-ES) polymers, or the polymers are selected among polyamidoamine (PAMAM) dendrimers functionalized with polyaniline (PANI), polyaniline emeraldine base (PANI-EB) and polyaniline emeraldine salt (PANI-ES) polymers.
