    • Different-Length Hydrazone Activated Polymers for Plasmid DNA Condensation and Cellular Transfection 

      Priegue Caamaño, Juan Manuel; Lostalé Seijo, Irene; Crisan, Daniel; Granja Guillán, Juan Ramón; Fernández Trillo, Francisco; Montenegro García, Javier (American Chemical Society, 2018)
      The recent advances in genetic engineering demand the development of conceptually new methods to prepare and identify efficient vectors for the intracellular delivery of different nucleotide payloads ranging from short ...
    • Dynamic chiral PPA–AgNP nanocomposites: aligned silver nanoparticles decorating helical polymers 

      Nuñez Martínez, Manuel; Arias López, Sandra; Quiñoá Cabana, Emilio; Riguera Vega, Ricardo; Freire Iribarne, Félix Manuel (ACS Publications, 2021)
      A novel approach to prepare stimulus-sensitive nanocomposites is described, based on a dynamic helical polymer, chiral poly(phenylacetylene) (PPA), and silver nanoparticles. To preserve the dynamic helical behavior of PPA ...
    • In situ functionalized polymers for siRNA delivery 

      Martínez Costas, José Manuel; Fernández Trillo, Francisco; Montenegro García, Javier; Granja Guillán, Juan Ramón; Priegue Caamaño, Juan Manuel; Crisan, Daniel (WILEY-VCH Verlag GmbH, 2016-04-21)
      A new method is reported herein for screening the biological activity of functional polymers across a consistent degree of polymerization and in situ, that is, under aqueous conditions and without purification/isolation ...
    • Merging supramolecular and covalent helical polymers: four helices within a single scaffold 

      Fernández Villar, Zulema; Fernández Rodríguez, Berta; Quiñoá Cabana, Emilio; Freire Iribarne, Félix Manuel (ACS Publications, 2021)
      Supramolecular and covalent polymers share multiple structural effects such as chiral amplification, helical inversion, sergeants and soldiers, or majority rules, among others. These features are related to the axial helical ...
    • Novel Cd (II) Coordination Polymers Afforded with EDTA or Trans-1,2-Cdta Chelators and Imidazole, Adenine, or 9-(2-Hydroxyethyl) Adenine Coligands 

      Belmont Sánchez, Jeannette Carolina; García Rubiño, María Eugenia; Frontera, Antonio; Matilla Hernández, Antonio; Castiñeiras Campos, Alfonso; Niclós Gutiérrez, Juan (MDPI, 2020)
      Three mixed-ligands of Cd(II) coordination polymers were unintentionally obtained: {[Cd(µ3-EDTA)(Him)·Cd(Him)(H2O)2]·H2O}n (1), {[Cd(µ4-CDTA)(Hade)·Cd(Hade)2]}n (2), and {[Cd(µ3-EDTA)(H2O)·Cd(H9heade)(H2O)]·2H2O}n (3), ...
    • Polymeric Helical Structures à la Carte by Rational Design of Monomers 

      Cobos Cabrera, Scarlet Katherine; Rodríguez Riego, Rafael; Domarco Álvarez, Olaya; Fernández Rodríguez, Berta; Quiñoá Cabana, Emilio; Riguera Vega, Ricardo; Freire Iribarne, Félix Manuel (American Chemical Society, 2020)
      Preparation of helical structures à la carte by monomer design of dynamic helical polymers such as poly(phenylacetylene)s (PPAs) is a difficult task due to conformational freedom of the polyene backbone. Herein, we study ...
    • Reversible assembly of enantiomeric helical polymers: from fibers to gels 

      Leiras Fernández, Seila; Freire Iribarne, Félix Manuel; Quiñoá Cabana, Emilio; Riguera Vega, Ricardo (Royal Society of Chemistry, 2015)
      A novel class of stereocomplexes is described by the interaction of helically complementary poly(phenylacetylene)s (PPAs) carrying an a-methoxy-a-trifluoromethylphenylacetamide pendant group. The formation of the ...
    • Unveiling an NMR-invisible fraction of polymers in solution by saturation transfer difference 

      Novoa Carballal, Ramón; Martin-Pastor, Manuel; Fernandez-Megia, Eduardo (ACS Publications, 2021)
      The observation of signals in solution NMR requires nuclei with sufficiently large transverse relaxation times (T2). Otherwise, broad signals embedded in the baseline afford an invisible fraction of nuclei (IF). Based on ...
