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…
Controlling Colloidal Flow through a Microfluidic Y-junction
Alexander P. Antonov, Matthew Terkel, Fabian Jan Schwarzendahl +3
Microscopic particles flowing through narrow channels may accumulate near bifurcation points provoking flow reduction, clogging and ultimately chip breakage. Here we show that the…
Designing thermoplasmonic polymersomes for photothermal therapy
Valentino Barbieri, Javier González-Colsa, Diana Matias +6
Polymersomes, vesicles self-assembled from amphiphilic polymers, are promising nanocarriers for the targeted intracellular delivery of therapeutics. Integrating inorganic light-abs…
Density-polarity coupling in confined active polar films: asters, spirals, and biphasic orientational phases
Mathieu Dedenon, Claire A. Dessalles, Pau Guillamat +3
Topological defects in active polar fluids can organise spontaneous flows and influence macroscopic density patterns. Both of them play, for example, an important role during anima…
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…
Estimation of anisotropic bending rigidities and spontaneous curvatures of crescent curvature-inducing proteins from tethered-vesicle experimental data
Hiroshi Noguchi, Nikhil Walani, Marino Arroyo
The Bin/amphiphysin/Rvs (BAR) superfamily proteins have a crescent binding domain and bend biomembranes along the domain axis. However, their anisotropic bending rigidities and spo…
A theory for the flow of chemically-responsive polymer solutions: equilibrium and shear-induced phase separation
Marco De Corato, Marino Arroyo
Chemically-responsive polymers are macromolecules that respond to local variations of the chemical composition of the solution by changing their conformation, with notable examples…
A lattice Boltzmann model for self-diffusiophoretic particles near and at liquid-liquid interfaces
Lucas Palacios, Andrea Scagliarini, Ignacio Pagonabarraga
We introduce a novel mesoscopic computational model based on a multiphase-multicomponent lattice Boltzmann method for the simulation of self-phoretic particles in the presence of l…
Binding of anisotropic curvature-inducing proteins onto membrane tubes
Hiroshi Noguchi, Caterina Tozzi, Marino Arroyo
Bin/Amphiphysin/Rvs superfamily proteins and other curvature-inducing proteins have anisotropic shapes and anisotropically bend biomembrane. Here, we report how the anisotropic pro…
Guided accumulation of active particles by topological design of a second-order skin effect
Lucas S. Palacios, Serguei Tchoumakov, Maria Guix +3
Collective guidance of out-of-equilibrium systems without using external fields is a challenge of paramount importance in active matter, ranging from bacterial colonies to swarms o…
Combinatorial entropy behaviour leads to range selective binding in ligand-receptor interactions
Meng Liu, Azzurra Apriceno, Miguel Sipin +6
From viruses to nanoparticles, constructs functionalized with multiple ligands display peculiar binding properties that only arise from multivalent effects. Using statistical mecha…
Spontaneous polarization and locomotion of an active particle with surface-mobile enzymes
Marco De Corato, Ignacio Pagonabarraga, Loai K. E. A. Abdelmohsen +2
We examine a mechanism of locomotion of active particles whose surface is uniformly coated with mobile enzymes. The enzymes catalyze a reaction that drives phoretic flows but their…
Swimming Euglena respond to confinement with a behavioural change enabling effective crawling
Giovanni Noselli, Alfred Beran, Marino Arroyo +1
Some euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for…
Smart helical structures inspired by the pellicle of euglenids
Giovanni Noselli, Marino Arroyo, Antonio DeSimone
This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative…
Mechanics of axisymmetric sheets of interlocking and slidable rods
D. Riccobelli, G. Noselli, M. Arroyo +1
In this work, we study the mechanics of metamaterial sheets inspired by the pellicle of Euglenids. They are composed of interlocking elastic rods which can freely slide along their…
The Role of Stickiness in the Rheology of Semiflexible Polymers
Tom Golde, Martin Glaser, Cary Tutmarc +7
Semiflexible polymers form central structures in biological material. Modeling approaches usually neglect influences of polymer-specific molecular features aiming to describe semif…
Self-assembly of micro-machining systems powered by Janus micro-motors
C. Maggi, J. Simmchen, F. Saglimbeni +5
Integration of active matter in larger micro-devices can provide an embedded source of propulsion and lead to self-actuated micromachining systems that do not rely on any external…
Cross-stream migration of active particles
Jaideep Katuri, William E. Uspal, Juliane Simmchen +2
For natural microswimmers, the interplay of swimming activity and external flow can promote robust motion, e.g. propulsion against ("upstream rheotaxis") or perpendicular to the di…
Topographical pathways guide chemical microswimmers
Juliane Simmchen, Jaideep Katuri, William E. Uspal +3
Achieving control over the directionality of active colloids is essential for their use in practical applications such as cargo carriers in microfluidic devices. So far, guidance o…
