Dielectric nanotomography based on electrostatic force microscopy: A numerical analysis
Rene Fabregas, Gabriel Gomila
Electrostatic force microscopy (EFM) can image nanoscale objects buried below the surface. Here, we theoretically show that this capability can be used to obtain nanotomographic in…
Stronger when wet: Water-resistant chitinous objects via zero-waste coordination with metal ions
Akshayakumar Kompa, Javier G Fernandez
Plastics have become integral to our society due to their durability and water stability, which is achieved through strong intermolecular interactions. However, these properties al…
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…
Live magnetic observation of parahydrogen hyperpolarization dynamics
James Eills, Morgan W. Mitchell, Irene Marco Rius +1
Hyperpolarized nuclear spins in molecules exhibit high magnetization that is unachievable by classical polarization techniques, making them widely used as sensors in physics, chemi…
Robust Parahydrogen-Induced Polarization at High Concentrations
Laurynas Dagys, Martin C. Korzeczek, Anna J. Parker +7
Parahydrogen-Induced Polarization (PHIP) is a potent technique for generating target molecules with high nuclear spin polarization. The PHIP process involves a chemical reaction be…
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…
Real-time polarimetry of hyperpolarized C nuclear spins using an atomic magnetometer
Kostas Mouloudakis, Sven Bodenstedt, Marc Azagra +3
We introduce a method for non-destructive quantification of nuclear spin polarization, of relevance to hyperpolarized spin tracers widely used in magnetic resonance from spectrosco…
Non-affine mechanics of entangled networks inspired by intermediate filaments
M. Pensalfini, T. Golde, X. Trepat +1
Inspired by massive intermediate filament (IF) reorganization in superstretched epithelia, we examine computationally the principles controlling the mechanics of a set of entangled…
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…
Depth mapping of metallic nanowire polymer nanocomposites by scanning dielectric microscopy
H. Balakrishnan, R. Millan-Solsona, M. Checa +3
Polymer nanocomposite materials based on metallic nanowires are widely investigated as transparent and flexible electrodes or as stretchable conductors and dielectrics for biosensi…
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…
