Chirality is a fundamental property which plays a major role in chemistry, physics, biological
systems and materials science. Chiroptical artificial molecular motors (AMMs) are a class of …

Microscopic active droplets are able to swim autonomously in viscous flows. This puzzling
feature stems from solute exchanges with the surrounding fluid via surface reactions or their …

Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Droplets abound in nature and technology. In general, they are multicomponent, and, when
out of equilibrium, have gradients in concentration, implying flow and mass transport …

Phase separating systems that are maintained away from thermodynamic equilibrium via
molecular processes represent a class of active systems, which we call active emulsions …

Liquid crystals (LCs) are ubiquitous in display technologies. The orientational ordering in the
nematic phase of LCs gives rise to structural anisotropy, the ability to form topological …

Chemotaxis and autochemotaxis play an important role in many essential biological
processes. We present a self-propelling artificial swimmer system that exhibits chemotaxis …

We report spontaneous motion in a fully biocompatible system consisting of pure water
droplets in an oil-surfactant medium of squalane and monoolein. Water from the droplet is …

The extraordinary responsiveness and large diversity of self-assembled structures of liquid
crystals are well documented and they have been extensively used in devices like displays …

Swimming droplets are artificial microswimmers based on liquid droplets that show self-
propelled motion when immersed in a second liquid. These systems are of tremendous …
