Stacking correlation length in single-stranded DNA
Xavier Viader-Godoy, Maria Manosas, Felix Ritort
Base stacking is crucial in nucleic acid stabilization, from DNA duplex hybridization to single-stranded DNA (ssDNA) protein binding. While stacking energies are tiny in ssDNA, the…
Characterizing the Hard and Soft Nanoparticle-Protein Corona with Multilayer Adsorption
Oriol Vilanova, Alberto Martinez-Serra, Marco P Monopoli +1
Nanoparticles (NPs) in contact with biological fluid adsorb biomolecules into a corona. This corona comprises proteins that strongly bind to the NP (hard corona) and loosely bound…
Curvature induces and enhances transport of spinning colloids through narrow channels
Eric Cereceda-López, Marco De Corato, Ignacio Pagonabarraga +3
The effect of curvature and how it induces and enhances the transport of colloidal particles driven through narrow channels represent an unexplored research avenue. Here we combine…
Photocatalytic magnetic microgyroscopes with activity-tunable precessional dynamics
Dolachai Boniface, Arthur V. Straube, Pietro Tierno
Magnetic nano/microrotors are passive elements that spin around an axis due to an external rotating field while remaining confined to a close plane. They have been used to date in…
Active nematic pumps
Ignasi Vélez-Ceron, Rodrigo C. V. Coelho, Pau Guillamat +4
Microfluidics involves the manipulation of flows at the microscale, typically requiring external power sources to generate pressure gradients. Alternatively, harnessing flows from…
Bidirectional Zigzag Growth from Clusters of Active Colloidal Shakers
Gaspard Junot, Andrés Javier Manzano González, Pietro Tierno
Driven or self-propelling particles moving in viscoelastic fluids recently emerge as novel class of active systems showing a complex yet rich set of phenomena due to the non-Newton…
Large scale zigzag pattern emerging from circulating active shakers
Gaspard Junot, Marco De Corato, Pietro Tierno
We report the emergence of large zigzag bands in a population of reversibly actuated magnetic rotors that behave as active shakers, namely squirmers that shake the fluid around the…
Small-Angle X-ray Scattering Unveils the Internal Structure of Lipid Nanoparticles
Francesco Spinozzi, Paolo Moretti, Diego Romano Perinelli +6
Lipid nanoparticles own a remarkable potential in nanomedicine, only partially disclosed. While the clinical use of liposomes and cationic lipid-nucleic acid complexes is well-esta…
Probing active nematics with in-situ microfabricated elastic inclusions
Ignasi Vélez-Cerón, Pau Guillamat, Francesc Sagués +1
In this work, we report a direct measurement of the forces exerted by a tubulin/kinesin active nematic gel as well as its complete rheological characterization, including the quant…
GHz sample excitation at the ALBA-PEEM
Muhammad Waqas Khaliq, José M. Álvarez, Antonio Camps +9
We describe a setup that is used for high-frequency electrical sample excitation in a cathode lens electron microscope with the sample stage at high voltage as used in many synchro…
Hydrophobic homopolymer's coil-globule transition and adsorption onto a hydrophobic surface under different conditions
Bernat Durà Faulí, Valentino Bianco, Giancarlo Franzese
Unstructured proteins can modulate cellular responses to environmental conditions by undergoing coil-globule transitions and phase separation. However, the molecular mechanisms of…
Hydrodynamic interactions hinder transport of flow-driven colloidal particles
Dominik Lips, Eric Cereceda-López, Antonio Ortiz-Ambriz +3
The flow-driven transport of interacting micron-sized particles occurs in many soft matter systems spanning from the translocation of proteins to moving emulsions in microfluidic d…
Using Car-Parrinello simulations and microscopic order descriptors to reveal two locally favored structures with distinct molecular dipole moments and dynamics in ambient liquid water
Ioannis Skarmoutsos, Giancarlo Franzese, Elvira Guardia
Water is essential for life and technological applications, mainly for its unique thermodynamic and dynamic properties, often anomalous or counterintuitive. These anomalies result…
Vesicle formation induced by thermal fluctuations
Andreu F. Gallen, J. Roberto Romero-Arias, Rafael A. Barrio +1
The process of fission and vesicle formation depends on the geometry of the membrane that will split. For instance, a flat surface finds it difficult to form vesicles because of th…
Rotating Micro-Spheres for Adsorption Monitoring at a Fluid Interface
J. Martín-Roca, M. Jiménez, F. Ortega +4
Hypothesis: A broad range of phenomena, such as emulsification and emulsion stability, foam formation or liquid evaporation, are closely related to the dynamics of adsorbing colloi…
Hydrodynamic interactions can induce jamming in flow-driven systems
Eric Cereceda-López, Dominik Lips, Antonio Ortiz-Ambriz +3
Hydrodynamic interactions between fluid-dispersed particles are ubiquitous in soft matter and biological systems and they give rise to intriguing collective phenomena. While it was…
Collective hydrodynamic transport of magnetic microrollers
Gaspard Junot, Andrejs Cebers, Pietro Tierno
We investigate the collective transport properties of microscopic magnetic rollers that propel close to a surface due to a circularly polarized, rotating magnetic field. The applie…

Fabio Leoni, Carles Calero, Giancarlo Franzese
Nanoconfinement can drastically change the behavior of liquids, puzzling us with counterintuitive properties. Moreover, it is relevant in applications, including decontamination an…
Single-file dynamics of colloids in circular channels: time scales, scaling laws and their universality
Alejandro Villada-Balbuena, Antonio Ortiz-Ambriz, Pavel Castro-Villarreal +3
In colloidal systems, Brownian motion emerges from the massive separation of time and length scales associated to characteristic dynamics of the solute and solvent constituents. Th…
