    • Macroscopic structures generated by microorganisms swimming in a fluid 

      Alarcón, Francisco; Pagonabarraga, Ignacio (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      It is known that active particles induce emerging patterns as a result of their dynamic interactions, giving rise to amazing collective motions, such as swarming or clustering. Here we present a systematic numerical ...
    • Polarized cortical tension drives zebrafish epiboly movements 

      Hernández-Vega, Amayra; Marsal, María; Pouille, Philippe-Alexandre; Tosi, Sebastien; Colombelli, Julien; Luque, Tomás; Navajas, Daniel; Pagonabarraga, Ignacio; Martín-Blanco, Enrique (EMBOpress, 2016-11-09)
      Article
      Open Access
      The principles underlying the biomechanics of morphogenesis are largely unknown. Epiboly is an essential embryonic event in which three tissues coordinate to direct the expansion of the blastoderm. How and where forces ...
    • Propulsion and energetics of a minimal magnetic microswimmer 

      Calero, Carles; García Torres, José Manuel; Ortiz, Antonio; Sagues, Francesc; Pagonabarraga, Ignacio; Tierno, Pietro (Royal Society of Chemistry, 2020-07-28)
      Article
      Open Access
      In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled in water upon application of a swinging ...
    • Self-propulsion of active colloids via ion release: theory and experiments 

      Corato, Marco de; Arqué, Xavier; Patiño, Tania; Arroyo Balaguer, Marino; Sanchez Ordoñez, Samuel; Pagonabarraga, Ignacio (American Institute of Physics (AIP), 2020-03-13)
      Article
      Open Access
      We study the self-propulsion of a charged colloidal particle that releases ionic species using theory and experiments. We relax the assumptions of thin Debye length and weak nonequilibrium effects assumed in classical ...
