Non-additivity in many-body interactions between membrane-deforming spheres increases disorder
Ali Azadbakht, Thomas R. Weikl, Daniela J. Kraft
Membrane-induced interactions have been predicted to be important for the organization of membrane proteins. Measurements of the interactions between two and three membrane deformi…
Designing highly efficient lock-and-key interactions in anisotropic active particles
Solenn Riedel, Ludwig A. Hoffmann, Luca Giomi +1
Cluster formation of microscopic swimmers is key to the formation of biofilms and colonies, efficient motion and nutrient uptake, but, in the absence of other interactions, require…
Soft and stiff normal modes in floppy colloidal square lattices
Julio Melio, Silke E. Henkes, Daniela J. Kraft
Floppy microscale spring networks are widely studied in theory and simulations, but no well-controlled experimental system currently exists. Here, we show that square lattices cons…
Optimality in superselective surface binding by multivalent DNA nanostars
Christine Linne, Eva Heemskerk, Jos Zwanikken +2
Weak multivalent interactions govern a large variety of biological processes like cell-cell adhesion and virus-host interactions. These systems distinguish sharply between surfaces…
Three-Body Interactions of Lipid Membrane-Deforming Colloidal Spheres
Ali Azadbakht, Billie Meadowcroft, Juraj Májek +2
Many cell functions require a concerted effort from multiple membrane proteins, for example, for signaling, cell division, and endocytosis. One contribution to their successful sel…
Wrapping pathways of anisotropic dumbbell particles by giant unilamellar vesicles
Ali Azadbakht, Billie Meadowcroft, Thijs Varkevisser +2
Endocytosis is a key cellular process involved in the uptake of nutrients, pathogens or the diagnosis and therapy of diseases. Most studies have focused on spherical objects, where…
Flexible Colloidal Molecules with Directional Bonds and Controlled Flexibility
Yogesh Shelke, Fabrizio Camerin, Susana Marín-Aguilar +3
Colloidal molecules are ideal model systems for mimicking real molecules and can serve as versatile building blocks for the bottom-up self-assembly of flexible and smart materials.…
Brownian motion of flexibly-linked colloidal rings
Ruben Verweij, Julio Melio, Indrani Chakraborty +1
Ring, or cyclic, polymers have unique properties compared to linear polymers, due to their topologically closed structure that has no beginning or end. Experimental measurements on…
Exploiting anisotropic particle shape to electrostatically assemble colloidal molecules with high yield and purity
Yogesh Shelke, Susana Marín-Aguilar, Fabrizio Camerin +2
Hypothesis: Colloidal molecules with anisotropic shapes and interactions are powerful model systems for deciphering the behavior of real molecules and building units for creating m…
Self-assembly dynamics of reconfigurable colloidal molecules
Indrani Chakraborty, Daniel J. G. Pearce, Ruben W. Verweij +3
Colloidal molecules are designed to mimic their molecular analogues through their anisotropic shape and interactions. However, current experimental realizations are missing the str…
Conformations and diffusion of flexibly linked colloidal chains

For biologically relevant macromolecules such as intrinsically disordered proteins, internal degrees of freedom that allow for shape changes have a large influence on both the moti…
Direct visualization of superselective colloid-surface binding mediated by multivalent interactions
Christine Linne, Daniele Visco, Stefano Angioletti-Uberti +2
Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and…
Activity-induced microswimmer interactions and cooperation in one-dimensional environments
