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 …

Self-propelled droplets are a class of active matter systems composed of one fluid dispersed
in another immiscible fluid. Despite the inherent spherical symmetry in the initial droplet …

Motility is the capacity for living organisms to move autonomously and with purpose, and is
essential to life. The transition from abiotic chemistry into motile cellular compartments has …

A variety of moving objects driven by chemical energy have been reported. In this
Minireview, we focus on self‐propelled objects driven by interfacial tension and explain …

Traveling waves are common in biological and synthetic systems, including the recent
discovery that silver (Ag) colloids form traveling motion waves in H2O2 and under light …

The physical origin of behaviour in biological organisms is distinct from those of non-living
systems in one significant way: organisms exhibit intentionality or goal-directed behaviour …

Interfacial chemical dynamics on a droplet generate various self-propelled motions. For
example, ballistic and random motions arise depending on the physicochemical conditions …

Spontaneous periodicity is widely found in many biological and synthetic systems, and
designing colloidal motors that mimic this feature may not only facilitate our understanding of …

Self-reproducing molecules abound in nature where they support growth and motion of
living systems. In artificial settings, chemical reactions can also show complex kinetics of …

The place of living organisms in the natural world is a nearly perennial question in
philosophy and the sciences; how can inanimate matter yield animate beings? A dominant …
