Active spinners drive passive matter into chiral rotors
Dennis Schorn, Anpuj Nair S, Stijn van der Ham +2
Active spinners inject angular momentum into their surroundings without persistent translation, providing a route to chiral active matter distinct from self-propelled particles mov…
Shape anisotropy governs organization of active rods: Swarming, turbulence, flocking, and jamming
Yogesh Shelke, Anpuj Nair S, Hanumantha Rao Vutukuri
Shape anisotropy of individual building blocks plays a crucial role in creating exotic structures and controlling phase behavior in equilibrium systems. We present a combined exper…
Programmable Persistent Random Walks in Active Brownian Particles Govern Emergent Dynamics
Tarun Sunkesula Raghavendra, Yogesh Shelke, Stijn van der Ham +2
Self-propelled particles serve as minimal models for emulating the dynamic self-organization of microorganisms, yet most synthetic systems remain limited to a single mode of motion…
Dynamic bidirectional coupling of membrane morphology and rod organization in flexible vesicles
Stijn van der Ham, André F. V. Matias, Marjolein Dijkstra +1
The ordering of rod-like particles in soft, deformable containers emerges from the interplay of anisotropic interactions, geometric confinement, and boundary compliance. This compe…
From shallow to full wrapping: geometry and deformability dictate lipid vesicle internalization
Stijn van der Ham, Alexander Brown, Halim Kusumaatmaja +1
The deformability of vesicles critically influences their engulfment by lipid membranes, a process central to endocytosis, viral entry, drug delivery, and intercellular transport.…
Unifying atoms and colloids near the glass transition through bond-order topology
Laura Stricker, Peter M. Derlet, Ahmet Faik Demirörs +2
In this combined experimental and simulation study, we utilize bond-order topology to quantitatively match particle volume fraction in mechanically uniformly compressed colloidal s…
Role of shape in particle-lipid membrane interactions: from surfing to full engulfment
Stijn van der Ham, Jaime Agudo-Canalejo, Hanumantha Rao Vutukuri
Understanding and manipulating the interactions between foreign bodies and cell membranes during endo- and phagocytosis is of paramount importance, not only for the fate of living…
A colloidal viewpoint on the finite sphere packing problem: the sausage catastrophe
Susana Marín-Aguilar, Fabrizio Camerin, Stijn van der Ham +3
It is commonly believed that the most efficient way to pack a finite number of equal-sized spheres is by arranging them tightly in a cluster. However, mathematicians have conjectur…
Light-switchable propulsion of active particles with reversible interactions
Hanumantha Rao Vutukuri, Maciej Lisicki, Eric Lauga +1
Active systems such as microorganisms and self-propelled particles show a plethora of collective phenomena, including swarming, clustering, and phase separation. Control over the p…
Sculpting vesicles with active particles: Less is more
Hanumantha Rao Vutukuri, Masoud Hoore, Clara Abaurrea-Velasco +6
Biological cells are able to generate intricate structures and respond to external stimuli, sculpting their membrane from within. Simplified biomimetic systems can aid in understan…
Rational design and dynamics of self-propelled colloidal bead chains: from rotators to flagella
Hanumantha Rao Vutukuri, Bram Bet, René van Roij +2
The quest for designing new self-propelled colloids is fuelled by the demand for simple experimental models to study the collective behaviour of their more complex natural counterp…
Fabrication of polyhedral particles from spherical colloids and their self-assembly into rotator phases
Hanumantha Rao Vutukuri, Arnout Imhof, Alfons van Blaaderen
Particle shape is a critical parameter that plays an important role in self-assembly, for example, in designing targeted complex structures with desired properties. In the last dec…
Colloidal analogues of charged and uncharged polymer chains with tunable stiffness
Hanumantha Rao Vutukuri, Ahmet Faik Demirörs, Bo Peng +3
Herein, we describe new methods to produce colloidal particle chains of three stiffness regimes that can be observed on a single-particle level, that is, on the level of the monome…
Rotational averaging-out gravitational sedimentation of colloidal dispersions and phenomena
Djamel El Masri, Teun Vissers, Stephane Badaire +7
We report on the differences between colloidal systems left to evolve in the earth's gravitational field and the same systems for which a slow continuous rotation averaged out the…
