Temperature‐responsive microgels find widespread applications as soft materials for
designing actuators in microfluidic systems, as carriers for drug delivery or catalysts, as …

Here we show that microgels trapped at a solid wall can issue liquid flow and transport over
distances several times larger than the particle size. The microgel consists of cross-linked …

We report on the adsorption kinetics of azobenzene-containing surfactants on solid surfaces
of different hydrophobicity. The understanding of this processes is of great importance for …

Owing to their property to alter their surface‐activity upon the irradiation with light,
photoswitchable surfactants have gained tremendous interest in colloidal science. Their …

Active matter contains self-propelled units able to convert stored or ambient free energy into
motion. Such systems demonstrate amazing features related to the phenomenon of self …

We consider sedimented at a solid wall particles that are immersed in water containing small
additives of photosensitive ionic surfactants. It is shown that illumination with an appropriate …

We discuss an electro-osmotic flow near charged porous coatings of a finite hydrodynamic
permeability, impregnated with an outer electrolyte solution. It is shown that their …

We report on guided and self-organized motion of ensembles of mesoporous colloidal
particles that can undergo dynamic aggregation or separation upon exposure to light. The …

Ionic complexation of azobenzene-containing surfactants with any type of oppositely
charged soft objects allows for making them photo-responsive in terms of their size, shape …

Natural or artificial active objects can demonstrate mirror asymmetry of collective motion
when they are moving coherently in a vortex. The majority of known cases related to the …
