      Microstructures from small phenylalanine-based peptides have attracted great attention lately because these compounds are considered to be a new class of tunable materials. In spite of the extensive studies on uncapped ...
    • Electroactive polymer-peptide conjugates for adhesive biointerfaces 

      Maione, Silvana; Gil, Ana M.; Fabregat Jové, Georgina; Valle Mendoza, Luis Javier del; Triguero Enguídanos, Jordi; Laurent, A.; Jacquemin, Denis; Estrany Coda, Francesc; Jimenez Sanz, Ana Isabel; Zanuy Gomara, David; Cativiela, Carlos; Alemán Llansó, Carlos (Royal Society of Chemistry, 2015-01-01)
      Article
      Open Access
      Electroactive polymer-peptide conjugates have been synthesized by combining poly(3,4-ethylenedioxythiophene), a polythiophene derivative with outstanding properties, and an Arg-Gly-Asp (RGD)-based peptide in which Gly has ...
    • Heterochirality restricts the self-assembly of phenylalanine dipeptides capped with highly aromatic groups
