Self-reconfiguring colloidal active matter
Stefania Ketzetzi, Lorenzo Caprini, Vivien Willems +3
Cells and microorganisms employ dynamic shape changes to enable steering and avoidance for efficient spatial exploration and collective organization. In contrast, active colloids,…
Gating and tunable confinement of active colloids within patterned environments
Carolina van Baalen, Stefania Ketzetzi, Anushka Tintor +1
Active colloidal particles typically exhibit a pronounced affinity for accumulating and being captured at boundaries. Here, we engineer long-range repulsive interactions between co…
Tunable Assembly of Confined Janus Microswimmers in Sub-kHz Electic Fields under Gravity
Carolina van Baalen, Laura Alvarez, Robert Style +1
Active systems comprising micron-sized self-propelling units, also termed microswimmers, are promising candidates for the bottom-up assembly of small structures and reconfigurable…
